Batch trying to log information from a REG_MULTI_SZ value - batch-file

Have seen - Assigning newline character to a variable in a batch script
I am wanting to take a REG_MULTI_SZ and split to multiple lines..
For example, we have:
if %PROCESSOR_ARCHITECTURE% == AMD64 SET ApacheKey="HKLM\SOFTWARE\Wow6432Node\Apache Software Foundation\Procrun 2.0\Tomcat6\Parameters\Java"
if NOT %PROCESSOR_ARCHITECTURE% == AMD64 SET ApacheKey="HKLM\SOFTWARE\Apache Software Foundation\Procrun 2.0\Tomcat6\Parameters\Java"
POWERSHELL "Get-ItemProperty 'HKLM:%ApacheKey%' |select -ExpandProperty Options" >> somelog.txt
Thanks to the response below and the post found at - How to read multi line multi string registry entries in PowerShell?
as this is now working!
Please note: I cannot use vbs (well I could) but would rather not as I have to codesign my scripts.
Can break out the "\0" delimiters. The issue that I have right now is that I type in echo %SETTINGS% from the command-line and I can see the new lines.. Probably going to have to PIPE the original variable to a text file. Read in (type) the file and if the "\0" is found to echo. which should write the file properly.
The original log shows:
-Dcatalina.base=C:\tomcat\0-Dcatalina.home=C:\tomcat\0-Djava.endorsed.dirs=C:\tomcat\endorsed\0-Djava.io.tmpdir=C:\tomcat\temp\0-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager\0-Djava.util.logging.config.file=C:\tomcat\conf\logging.properties\0-Dcom.sun.management.jmxremote\0-Dcom.sun.management.jmxremote.port=1092\0-Dcom.sun.management.jmxremote.ssl=false\0-Dcom.sun.management.jmxremote.authenticate=false\0-XX:MaxPermSize=256m\0-Xmx1024m\0-Xms1024m\0-Xverify:none\0-XX:+UseConcMarkSweepGC\0-XX:+UseParNewGC\0-XX:MinHeapFreeRatio=40\0-XX:MaxHeapFreeRatio=60\0-XX:MaxGCPauseMillis=200
What I want it to show is:
-Dcatalina.base=C:\tomcat
-Dcatalina.home=C:\tomcat
-Djava.endorsed.dirs=C:\tomcat\endorsed
-Djava.io.tmpdir=C:\tomcat\temp

It can be simple using Vbscript working with your batch script:
:: Create readMulti.vbs
(
echo/Const HKEY_LOCAL_MACHINE = ^&H80000002
echo/strComputer = "."
echo/Set oReg=GetObject^("winmgmts:{impersonationLevel=impersonate}!\\" ^& _
echo/ strComputer ^& "\root\default:StdRegProv"^)
echo/strKeyPath = "SOFTWARE\Apache Software Foundation\Procrun 2.0\tomcat6\Parameters\Java"
echo/strValueName = "Options"
echo/oReg.GetMultiStringValue HKEY_LOCAL_MACHINE,strKeyPath, _
echo/ strValueName,arrValues
echo/For Each strValue In arrValues
echo/ Wscript.Echo strValue
echo/Next)>readMulti.vbs
for /f "tokens=*" %%a in ('cscript //nologo readMulti.vbs') do (echo/%%a>>log.txt)
del readMulti.vbs

Remove empty lines and spaces from .txt-File with Batch [duplicate]

What is the Windows batch equivalent of the Linux shell command echo -n which suppresses the newline at the end of the output?
The idea is to write on the same line inside a loop.
Using set and the /p parameter you can echo without newline:
C:\> echo Hello World
Hello World
C:\> echo|set /p="Hello World"
Hello World
C:\>
Source
Using: echo | set /p= or <NUL set /p= will both work to suppress the newline.
However, this can be very dangerous when writing more advanced scripts when checking the ERRORLEVEL becomes important as setting set /p= without specifying a variable name will set the ERRORLEVEL to 1.
A better approach would be to just use a dummy variable name like so:
echo | set /p dummyName=Hello World
This will produce exactly what you want without any sneaky stuff going on in the background as I had to find out the hard way, but this only works with the piped version; <NUL set /p dummyName=Hello will still raise the ERRORLEVEL to 1.
The simple SET /P method has limitations that vary slightly between Windows versions.
Leading quotes may be stripped
Leading white space may be stripped
Leading = causes a syntax error.
See http://www.dostips.com/forum/viewtopic.php?f=3&t=4209 for more information.
jeb posted a clever solution that solves most of the problems at Output text without linefeed, even with leading space or = I've refined the method so that it can safely print absolutely any valid batch string without the new line, on any version of Windows from XP onward. Note that the :writeInitialize method contains a string literal that may not post well to the site. A remark is included that describes what the character sequence should be.
The :write and :writeVar methods are optimized such that only strings containing troublesome leading characters are written using my modified version of jeb's COPY method. Non-troublesome strings are written using the simpler and faster SET /P method.

As an addendum to #xmechanix's answer, I noticed through writing the contents to a file:
echo | set /p dummyName=Hello World > somefile.txt
That this will add an extra space at the end of the printed string, which can be inconvenient, specially since we're trying to avoid adding a new line (another whitespace character) to the end of the string.
Fortunately, quoting the string to be printed, i.e. using:
echo | set /p dummyName="Hello World" > somefile.txt
Will print the string without any newline or space character at the end.
A solution for the stripped white space in SET /P:
the trick is that backspace char which you can summon in the text editor EDIT for DOS. To create it in EDIT press ctrlP+ctrlH.
I would paste it here but this webpage can't display it. It's visible on Notepad though (it's werid, like a small black rectangle with a white circle in the center)
So you write this:
<nul set /p=.9 Hello everyone
The dot can be any char, it's only there to tell SET /P that the text starts there, before the spaces, and not at the "Hello".
The "9" is a representation of the backspace char that I can't display here. You have to put it instead of the 9, and it will delete the "." , after which you'll get this:
Hello Everyone
instead of:
Hello Everyone
I hope it helps
Here is another method, it uses Powershell Write-Host which has a -NoNewLine parameter, combine that with start /b and it offers the same functionality from batch.
NoNewLines.cmd
#ECHO OFF
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 1 - ';Write-Host -NoNewLine 'Result 2 - ';Write-Host -NoNewLine 'Result 3 - '"
PAUSE
Output
Result 1 - Result 2 - Result 3 - Press any key to continue . . .
This one below is slightly different, doesn't work exactly like the OP wants, but is interesting because each result overwrites the previous result emulating a counter.
#ECHO OFF
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 1 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 2 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 3 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 4 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 5 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 6 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 7 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 8 - '"
start /b /wait powershell.exe -command "Write-Host -NoNewLine 'Result 9 - '"
PAUSE
You can remove the newline using "tr" from gnuwin32 (coreutils package)
#echo off
set L=First line
echo %L% | tr -d "\r\n"
echo Second line
pause
By the way, if you are doing lots of scripting, gnuwin32 is a goldmine.
I made a function out of #arnep 's idea:
echo|set /p="Hello World"
here it is:
:SL (sameline)
echo|set /p=%1
exit /b
Use it with call :SL "Hello There"
I know this is nothing special but it took me so long to think of it I figured I'd post it here.
DIY cw.exe (console write) utility
If you don't find it out-of-the-box, off-the-shelf, you can DIY. With this cw utility you can use every kind of characters. At least, I'd like to think so. Please stress-test it and let me know.
Tools
All you need is .NET installed, which is very common nowadays.
Materials
Some characters typed/copy-pasted.
Steps
Create .bat file with the following content.
/* >nul 2>&1
#echo off
setlocal
set exe=cw
for /f "tokens=* delims=" %%v in ('dir /b /s /a:-d /o:-n "%SystemRoot%\Microsoft.NET\Framework\*csc.exe"') do set "csc=%%v"
"%csc%" -nologo -out:"%exe%.exe" "%~f0"
endlocal
exit /b %errorlevel%
*/
using System;
namespace cw {
class Program {
static void Main() {
var exe = Environment.GetCommandLineArgs()[0];
var rawCmd = Environment.CommandLine;
var line = rawCmd.Remove(rawCmd.IndexOf(exe),exe.Length).TrimStart('"');
line = line.Length < 2 ? "\r" : line.Substring(2) ;
Console.Write(line);
}
}
}
Run it.
Now you have a nice 4KB utility so you can delete the .bat.
Alternatively, you can insert this code as a subroutine in any batch, send the resulting .exe to %temp%, use it in your batch and delete it when you're done.
How to use
If you want write something without new line:
cw Whatever you want, even with "", but remember to escape ^|, ^^, ^&, etc. unless double-quoted, like in "| ^ &".
If you want a carriage return (going to the beginning of the line), run just
cw
So try this from command line:
for /l %a in (1,1,1000) do #(cw ^|&cw&cw /&cw&cw -&cw&cw \&cw)
From here
<nul set /p =Testing testing
and also to echo beginning with spaces use
echo.Message goes here
Maybe this is what your looking for, it's a old school script... :P
set nl=^& echo.
echo %nl%The%nl%new%nl%line%nl%is%nl%not%nl%apparent%nl%throughout%nl%text%nl%
echo only in prompt.
pause
or maybe your trying to replace a current line instead of writing to a new line?
you can experiment with this by removing the "%bs%" after the "." sign and also by spacing out the other "%bs%" after the "Example message".
for /f %%a in ('"prompt $H&for %%b in (1) do rem"') do set "bs=%%a"
<nul set /p=.%bs% Example message %bs%
pause
I find this really interesting because it uses a variable for a purpose other than what it is intended to do. as you can see the "%bs%" represents a backspace. The second "%bs%" uses the backspace to add spaces after the "Example message" to separate the "Pause command's output" without actually adding a visible character after the "Example message". However, this is also possible with a regular percentage sign.
Sample 1: This works and produces Exit code = 0. That is Good.
Note the "." , directly after echo.
C:\Users\phife.dog\gitrepos\1\repo_abc\scripts #
#echo.| set /p JUNK_VAR=This is a message displayed like Linux echo -n would display it ... & echo %ERRORLEVEL%
This is a message displayed like Linux echo -n would display it ... 0
Sample 2: This works but produces Exit code = 1. That is Bad.
Please note the lack of ".", after echo. That appears to be the difference.
C:\Users\phife.dog\gitrepos\1\repo_abc\scripts #
#echo | set /p JUNK_VAR=This is a message displayed like Linux echo -n would display it ... & echo %ERRORLEVEL%
This is a message displayed like Linux echo -n would display it ... 1
Inspired by the answers to this question, I made a simple counter batch script that keeps printing the progress value (0-100%) on the same line (overwritting the previous one). Maybe this will also be valuable to others looking for a similar solution.
Remark: The * are non-printable characters, these should be entered using [Alt + Numpad 0 + Numpad 8] key combination, which is the backspace character.
#ECHO OFF
FOR /L %%A in (0, 10, 100) DO (
ECHO|SET /P="****%%A%%"
CALL:Wait 1
)
GOTO:EOF
:Wait
SET /A "delay=%~1+1"
CALL PING 127.0.0.1 -n %delay% > NUL
GOTO:EOF
You can suppress the new line by using the set /p command. The set /p command does not recognize a space, for that you can use a dot and a backspace character to make it recognize it. You can also use a variable as a memory and store what you want to print in it, so that you can print the variable instead of the sentence. For example:
#echo off
setlocal enabledelayedexpansion
for /f %%a in ('"prompt $H & for %%b in (1) do rem"') do (set "bs=%%a")
cls
set "var=Hello World! :)"
set "x=0"
:loop
set "display=!var:~%x%,1!"
<nul set /p "print=.%bs%%display%"
ping -n 1 localhost >nul
set /a "x=%x% + 1"
if "!var:~%x%,1!" == "" goto end
goto loop
:end
echo.
pause
exit
In this way you can print anything without a new line. I have made the program to print the characters one by one, but you can use words too instead of characters by changing the loop.
In the above example I used "enabledelayedexpansion" so the set /p command does not recognize "!" character and prints a dot instead of that. I hope that you don't have the use of the exclamation mark "!" ;)
Use EchoX.EXE from the terrific "Shell Scripting Toolkit" by Bill Stewart
How to suppress the linefeed in a Windows Cmd script:
#Echo Off
Rem Print three Echos in one line of output
EchoX -n "Part 1 - "
EchoX -n "Part 2 - "
EchoX "Part 3"
Rem
gives:
Part 1 - Part 2 - Part 3
{empty line}
d:\Prompt>
The help for this usage is:
Usage: echox [-n] message
-n Do not skip to the next line.
message The text to be displayed.
The utility is smaller than 48K, and should live in your Path. More things it can do:- print text without moving to the next line- print text justified to the left, center, or right, within a certain width- print text with Tabs, Linefeeds, and Returns- print text in foreground and background colors
The Toolkit includes twelve more great scripting tricks.
The download page also hosts three other useful tool packages.
I found this simple one-line batch file called "EchoPart.bat" to be quite useful.
#echo | set /p=%*
I could then write something like the line below even on an interactive CMD line, or as part of a shortcut. It opens up a few new possibilities.
echopart "Hello, " & echopart "and then " & echo Goodbye
And if you're using it in batch files, the texts can be got from parameter variables instead of immutable strings. For instance:
#echopart Hello %* & #echo , how are you?
So that executing this line in "SayHello.bat" allows:
or even...
Have a play, and have fun!
I believe there's no such option. Alternatively you can try this
set text=Hello
set text=%text% world
echo %text%
Echo with preceding space and without newline
As stated by Pedro earlier, echo without new line and with preceding space works (provided "9" is a true [BackSpace]).
<nul set /p=.9 Hello everyone
I had some issues getting it to work in Windows 10 with the new console but managed the following way.
In CMD type:
echo .◘>bs.txt
I got "◘" by pressing [Alt] + [8]
(the actual symbol may vary depending upon codepage).
Then it's easy to copy the result from "bs.txt" using Notepad.exe to where it's needed.
#echo off
<nul set /p "_s=.◘ Hello everyone"
echo: here
With jscript:
#if (#X)==(#Y) #end /*
#cscript //E:JScript //nologo "%~nx0" %*
#exit /b %errorlevel%
*/if(WScript.Arguments.Count()>0) WScript.StdOut.Write(WScript.Arguments.Item(0));
if it is called write.bat you can test it like:
call write.bat string & echo _Another_String_
If you want to use powershell but with cmd defined variables you can use:
set str=_My_StrinG_
powershell "Write-Host -NoNewline ""%str%"""" & echo #Another#STRING#
Late answer here, but for anyone who needs to write special characters to a single line who find dbenham's answer to be about 80 lines too long and whose scripts may break (perhaps due to user-input) under the limitations of simply using set /p, it's probably easiest to just to pair your .bat or .cmd with a compiled C++ or C-language executable and then just cout or printf the characters. This will also allow you to easily write multiple times to one line if you're showing a sort of progress bar or something using characters, as OP apparently was.

Batch Echo Style: write two files at once [duplicate]

I am trying to use the tee code written for a bat file but am having trouble implementing it in my code. I don't want to use any third party installs to solve the tee problem as I want the code to work if I format my computer in a year and want to run the program again.

I am trying to split the output so I can save the console output to a file while still being able to interact with the program that is running.
How can I get the Tee command to work properly with my .bat so I can split the output to both a file and the console.
Your attempt to call a batch function within a pipe will always fail because of how Windows pipes work - Windows instantiates both sides of the pipe via new CMD shells. See https://stackoverflow.com/a/8194279/1012053 for more info.
That Rob van der Woude version of a batch tee cannot possibly work for you because it uses a FOR /F to read the results of a command - the command must execute to completion before any lines are read. That won't work if you need user interaction during the execution of the command. With that version of tee you might as well simply redirect output to a file and then TYPE the file when finished. Obviously not what you want.
There are pure batch tricks that can get you closer, but I think there is still one problem that can't be solved with pure batch. Your executable may put a prompt on a line without issuing a new line. I believe pure native batch always reads entire lines (except when at end of stream). I'm not aware of a batch method to read character by character.
Slight correction - SET /P can read partial lines of piped input, but it has limitations that prevent it from being used for a robust batch tee solution: There is no way to know for sure when each line ends. It is limited to 1021 characters per "line". It strips control characters from the end of each "line". There is no way to tell when it has reached the end of the input stream.
But there is a simple solution - JScript or VBScript works like a champ, and doesn't require any special installs. Here is a hybrid JScript/batch script that should work for you. The JScript is poorly written with lots of room for improvement. For example, there is no error checking.
I save the script as tee.bat. The first required argument specifies the name of the file to write to. By default, the file is over-written if it already exists. If a second argument is provided (value doesn't matter), then the output is appended to the file instead.
#if (#X)==(#Y) #end /* Harmless hybrid line that begins a JScript comment
::--- Batch section within JScript comment that calls the internal JScript ----
#echo off
cscript //E:JScript //nologo "%~f0" %*
exit /b
----- End of JScript comment, beginning of normal JScript ------------------*/
var fso = new ActiveXObject("Scripting.FileSystemObject");
var mode=2;
if (WScript.Arguments.Count()==2) {mode=8;}
var out = fso.OpenTextFile(WScript.Arguments(0),mode,true);
var chr;
while( !WScript.StdIn.AtEndOfStream ) {
chr=WScript.StdIn.Read(1);
WScript.StdOut.Write(chr);
out.Write(chr);
}
Usage is pretty much like you would expect.
command.exe | tee.bat output.txt 1
The last 1 argument forces append mode. It could be any value besides 1
It is possible to put everything in one batch script as you seem to prefer.
#if (#X)==(#Y) #end /* Harmless hybrid line that begins a JScript comment
::--- Batch section within JScript comment ----------------------------
#echo off
::This block of code handles the TEE by calling the internal JScript code
if "%~1"=="_TEE_" (
cscript //E:JScript //nologo "%~f0" %2 %3
exit /b
)
::The rest of your batch script goes here
::This pipes to TEE in append mode
mycommand.exe | "%~f0" _TEE_ output.txt 1
exit /b
----- End of JScript comment, beginning of normal JScript ------------------*/
var fso = new ActiveXObject("Scripting.FileSystemObject");
var mode=2;
if (WScript.Arguments.Count()==2) {mode=8;}
var out = fso.OpenTextFile(WScript.Arguments(0),mode,true);
var chr;
while( !WScript.StdIn.AtEndOfStream ) {
chr=WScript.StdIn.Read(1);
WScript.StdOut.Write(chr);
out.Write(chr);
}
Update
For anyone with an academic interest in batch scripting, I've posted a pure native batch version of tee at Asynchronous native batch tee script over at DosTips. But this hybrid approach is my preferred scripting solution.

Batch %1 get path with whitespace

I have set up a batch file to be default to open .txt files. In an earlier question I found out that %1 gives me the path of the file which was actually calling the batch file. The Problem is: if the file name contains white space, it gets interpreted as multiple parameters.
Example:
opening file "C:\Users\Desktop\space true.txt"
%1 gives:"C:\Users\Desktop\space" and then %2 gives: "true.txt"
How could I get just the full file path with the name and white space without trying to do a loop to attempt to get the full path by combining %1%2%3%4...
UPDATE-----------------------
Sorry there was a miss communication. The code below is working. The trick was to put "%*" instead of "%1"
here the code:
#echo on
set var= "%*"
c:
cd "C:\Users\MyText Editor"
start javaw -jar "MyTextEditor.jar"%var%
pause
I do the whole changing the path, because the file which I double click and the the the batch file are in different directories. I had to change it to this.
UPDATE 2 --------------------------
The solution which worked best for me was from this fine gentlemen dbenham.
#echo off
pushd "C:\Users\MyText Editor"
start javaw -jar "MyTextEditor.jar" %*
The only complain I have is, that there is a case, where %* does not return the path with quotes. So I am searching for a final solution. Something like this "%~*" But this doesn't work.
Thanks in advance
The following is not quite correct - I thought the file associations would put quotes around the file name like drag and drop does. But I was mistaken
This line is the source of your problem:
set var= "%*"
When files are dragged onto your batch script, or if a text file is double clicked, any file name(s) containing space will automatically be enclosed within quotes.
When you add your own additional quotes, it defeats the purpose of the quotes - the space is no longer quoted.
For example, a string like "name with space.txt" is treated as a single arg, but with added quotes, ""name with space.txt"" becomes three arguments.
There is no need for your var variable. You can use %* directly in your START command.
#echo on
pushd "C:\Users\MyText Editor"
start javaw -jar "MyTextEditor.jar" %*
pause
I'm not sure the above works properly if multiple files are passed. I suspect you may want the following:
#echo on
pushd "C:\Users\MyText Editor"
for %%F in (%*) do start javaw -jar "MyTextEditor.jar" %%F
pause
There is one potential problem. Windows has a bug in that file names containing & are not automatically quoted as they should. See "Droplet" batch script - filenames containing ampersands for more info.
EDIT - The following should work
OK, I did some tests and I believe your best bet is to modify the command associated with .txt files.
I tested association changes via the command line. This must be done via an elevated command prompt with admin rights. On my machine I go to the Start menu, click on "All Programs", click on "Accessories" folder, right click "Command Prompt", and select "Run as administrator", then click "Yes" to allow the program to make changes to the system.
The following command will show which file type needs to be modified
assoc .txt
On my machine it reports .txt=txtfile, so txtfile is what must be modified using FTYPE.
I believe the following should work for you:
ftype txtfile="C:\pathToYourScrpt\yourScript.bat" "%1"
Obviously you would need to fix the path to your batch script :-)
Once you have made the change, the filename will automatically be quoted every time your script is invoked via a file association.
Your batch script can then look like the following, and it should work no matter how it is invoked (excepting drag and drop with file name containing & but no space):
#echo off
pushd "C:\Users\MyText Editor"
for %%F in (%*) do start javaw -jar "MyTextEditor.jar" %%F
It seems to me you should be able to eliminate the batch script and configure FTYPE TXTFILE to open your java editor directly. I should think something like the following:
ftype txtfile="c:\pathToJava\javaw.exe" -jar "C:\Users\MyText Editor\MyTextEditor.jar" "%1"
When calling your batch file, you must enclose your parameter in quotes if there is spaces in it.
E.g.: Batch.cmd "C:\Users\Desktop\space true.txt"

%*
Here's a list of characters.
& seperates commands on a line.
&& executes this command only if previous command's errorlevel is 0.
|| (not used above) executes this command only if previous command's errorlevel is NOT 0
> output to a file
>> append output to a file
< input from a file
| output of one command into the input of another command
^ escapes any of the above, including itself, if needed to be passed to a program
" parameters with spaces must be enclosed in quotes
+ used with copy to concatinate files. E.G. copy file1+file2 newfile
, used with copy to indicate missing parameters. This updates the files modified date. E.G. copy /b file1,,
%variablename% a inbuilt or user set environmental variable
!variablename! a user set environmental variable expanded at execution time, turned with SelLocal EnableDelayedExpansion command
%<number> (%1) the nth command line parameter passed to a batch file. %0 is the batchfile's name.
%* (%*) the entire command line.
%<a letter> or %%<a letter> (%A or %%A) the variable in a for loop. Single % sign at command prompt and double % sign in a batch file.
Your problem is really that the syntax of your set command is wrong. In a batch
file, a set command looks like this:
set "var=%1"
That will give you your variable exactly as received. If the user quoted it,
then the variable's value will have quotes around it. To remove the quotes,
you'd put a ~ in front of the number:
set "var=%~1"
Notice how the quotes go around the entire assignment, and not just around the
value you are assigning. It is not set var="%1".
If you use set var= "%*", you haven't really fixed the fundamental problem
that your syntax is wrong. Plus, often you really do want %1 and not the
entire command line.
Here is an example script to test various quoting behaviors:
#echo off
set var="%*"
echo 1. var="%%*" --^> [%var%] (wrong)
set "var=%*"
echo 2. "var=%%*" --^> [%var%]
set "var=%1"
echo 3. "var=%%1" --^> [%var%]
set "var=%~1"
echo 4. "var=%%~1" --^> [%var%]
set "var=%~2"
echo 5. "var=%%~2" --^> [%var%]
set "var=%~3"
echo 6. "var=%%~3" --^> [%var%]
And here is the output of that script. Note how arg1, arg2, and arg3 are all
quoted:
C:\batch> all_args.cmd "arg 1" "this is arg 2" "arg 3"
1. var="%*" --> [""arg 1" "this is arg 2" "arg 3""] (wrong)
2. "var=%*" --> ["arg 1" "this is arg 2" "arg 3"]
3. "var=%1" --> ["arg 1"]
4. "var=%~1" --> [arg 1]
5. "var=%~2" --> [this is arg 2]
6. "var=%~3" --> [arg 3]
You can see that numbers 4, 5, and 6 correctly pulled out their quoted arguments
and saved the value into var. You typically want to save the argument without quotes, and then quote it when you use it in your script. In other words, your script should look like this:
#echo on
set "var=%~1"
c:
cd "C:\Users\MyText Editor"
start javaw -jar "MyTextEditor.jar" "%var%"
pause
#echo on
set var= "%*"
c:
cd "C:\Users\MyText Editor"
start javaw -jar "MyTextEditor.jar"%var%
pause
Becomes removing redundant commands
start "" javaw -jar "C:\Users\MyText Editor\MyTextEditor.jar" "%*"
pause
Echo is already on unless turned off by you.
We don't put things into variables for no reason, and it's already in %*. It just makes convoluted code and removes meaning from the name of the variable.
When programming (unlike typing) we don't change paths (and cd /d C:\Users\MyText Editor does drive and folder anyway).
We specify full path on the command line. This makes your meaning quite clear.
The main problem was there was no space between .jar and %var% and start command the first quotes on the line are assumed to the CMD's window title. I would code the path to javaw and not use start. Start is asking the Windows' graphical shell to start the file, not CMD.
Here's a batch file that starts vbs files. I don't specify path to cscript as it's a Windows' command.
It's complexity is to make use fairly idiot proof and easy for others.
#echo off
Rem Make sure filter.vbs exists
set filter=

Use Batch File Processing To Remove Last Character

I have a process where an incoming file is csv and has trailing commas after the last entry.
I need to process this and send it out sans that final comma as it causes a verification error with the phantom "empty column"
Currently I've got this piece of code to write each line into a new file:
for /f "tokens=* delims=" %%x in (file.csv) do echo %%i >> test.txt
And I've been trying to use something like echo %string:~0,-1% to remove the trailing comma in conjunction but I'm not having much luck. I don't think %%i can be used the same as a string would be referenced with the above. I've tried writing %%i into a string but seems I've got that syntax wrong too.
[edit]
I do run the file through a vbs script to replace the commas with pipes (, = |) so if there's an easier way to do it as part of that process, in my searching of stackoverflow to try and resolve this prior to asking I found this line which I thought may help:
strNewText = strNewText.Substring(0,strNewText.Length-1)
strNewText being the variable holding the updated data, doesn't work though, now the find and replace text section doesn't actually run when I add that in:
rem CREATE Find And Replace Text VBS SCRIPT
echo Const ForReading = 1 > "%tmp%\fart.vbs"
echo Const ForWriting = 2 >> "%tmp%\fart.vbs"
echo strFileName = Wscript.Arguments(0) >> "%tmp%\fart.vbs"
echo strOldText = Wscript.Arguments(1) >> "%tmp%\fart.vbs"
echo strNewText = Wscript.Arguments(2) >> "%tmp%\fart.vbs"
echo Set objFSO = CreateObject("Scripting.FileSystemObject") >> "%tmp%\fart.vbs"
echo Set objFile = objFSO.OpenTextFile(strFileName, ForReading) >> "%tmp%\fart.vbs"
echo strText = objFile.ReadAll >> "%tmp%\fart.vbs"
echo objFile.Close >> "%tmp%\fart.vbs"
echo strNewText = Replace(strText, strOldText, strNewText) >> "%tmp%\fart.vbs"
echo strNewText = strNewText.Substring(0,strNewText.Length-1) >> "%tmp%\fart.vbs"
echo Set objFile = objFSO.OpenTextFile(strFileName, ForWriting) >> "%tmp%\fart.vbs"
echo objFile.WriteLine strNewText >> "%tmp%\fart.vbs"
echo objFile.Close >> "%tmp%\fart.vbs"
(all the echo's are because I generate the vbs during the batch runtime, I tend to find things easier when everything's done in the one file, this vbs file is then deleted later in the process).
#if (#This==#IsBatch) #then
#echo off
rem **** batch zone *********************************************************
type inputfile.csv | cscript //nologo //e:javascript "%~f0" > outputfile.csv
exit /b
#end
// **** Javascript zone *****************************************************
while (!WScript.StdIn.AtEndOfStream) WScript.StdOut.WriteLine(WScript.StdIn.ReadLine().replace(/,[\s,]+$/,''));
This is an hybrid batch/javascript file. Save as batch file, execute and the inputfile.csv file will be piped into cscript.exe that will execute the javascript code included in the same batch file, iterating over the piped data and deleting all commas and final spaces from last comma to end of line. Output from pipe is sent to outputfile.csv
EDITED - As stated in comments, maybe i missunderstood the question, and it is not necessary to remove commaS at the end of the lines, but only the final comma. In this case, the replace expression should be
... .replace(/,$/,''));
Probably the simplest solution for your problem would be sed for Windows:
C:\>sed "s/,$//" <in.csv >out.csv
You could also write a simple VBScript that does the same thing:
Set re = New RegExp
re.Pattern = ",$"
Do Until WScript.StdIn.AtEndOfStream
WScript.Echo re.Replace(WScript.StdIn.ReadLine, "")
Loop
Usage:
C:\>cscript //NoLogo script.vbs <in.csv >out.csv
PowerShell would be an even better option:
PS C:\> (Get-Content 'in.csv') -replace ',$' | Out-File 'out.csv'
I would not recommend using batch for this.
I'm not sure this will work, but since you only want the code to apply for the last line, I've tried implementing the code differently from your average for loop.
#echo off
setlocal enabledelayedexpansion
set previous=
set current=
ren file.csv file.tmp
3<file.tmp (
:loop
set previous=!current!
set /p current=<&3
if "!current!" == "!previous!" (
Echo !current:~0,-1! >> file.csv
) Else (
Echo !current! >> file.csv
goto :loop
)
)
type file.csv
Echo. &Echo Only delete if file.csv is not corrupt
del /p file.tmp
Endlocal
And that should about do what you want.

Print Batch results to a text file?

I created a batch file to lookup my external ip.
and it works well .
This is the code.
#echo off
>"%temp%\ip.vbs" echo Set objHTTP = CreateObject("MSXML2.XMLHTTP")
>>"%temp%\ip.vbs" echo Call objHTTP.Open("GET", "http://checkip.dyndns.org", False)
>>"%temp%\ip.vbs" echo objHTTP.Send()
>>"%temp%\ip.vbs" echo strHTML = objHTTP.ResponseText
>>"%temp%\ip.vbs" echo wscript.echo strHTML
for /f "tokens=7 delims=:<" %%a in ('cscript /nologo "%temp%\ip.vbs"') do set ip=%%a
echo %ip:~1%
pause
What i want is to Print the results to a text file named "IPlog.txt"
and every time i run the bat file it has to do the same thing and print the new results to the next line in the text file. So please can anyone help me with this.
... or change your
echo %ip:~1%
to
echo %ip:~1% >>IPlog.txt
to run your batch without the additional " >>IPlog.txt "
Please remove the pause command from your code and run the batch-file like this
mybatch.bat >> IPlog.txt
This will append the resulting ip address on to the log file IPLog.txt every time you run this batch file.
