I have a lot of shortcut urls in a directory.
C:\Users\Owner\Desktop\ReadItLaters>dir *.url /b
aaa.url
bbb.url
ccc.url
...
zzz.url
I want to pickup those url.
so I wrote command like this.
for %i in (*.url) do #type "%i" | find "URL="
that outputs like this.
URL=https://www.example.com/aaa.html
URL=https://www.example.com/bbb.html
URL=https://www.example.com/ccc.html
...
URL=https://www.example.com/zzz.html
It tastes nice. but I want to get url strings WITHOUT "URL=".
I wish to output like this.
https://www.example.com/aaa.html
https://www.example.com/bbb.html
https://www.example.com/ccc.html
...
https://www.example.com/zzz.html
How can I replace "URL=" to empty?
You can use substring, skipping the first 4 characters in your string: %_url:~4%
cmd/bat
for /f %%i in ('type *.url^|find "URL="')do set "_url=%%~i" && call echo/%_url:~4%
command-line
for /f %i in ('type *.url^|find "URL="')do set "_url=%~i" && call echo/%_url:~4%
Some further reading:
[√] Set
[√] For Loop
[√] For /F Loop
[√] Conditional Execution || && ...
[√] Substring in Set command (Refer: %_url:~4%)
use a for /f loop to process the lines:
for /f "tokens=2 delims==" %%a in ('type *.url 2^>nul^|find "URL="') do #echo %%a
or a bit saver (in case the URLs contain =)
for /f "tokens=1,* delims==" %%a in ('type *.url 2^>nul^|findstr /b "URL="') do #echo %%b
See for /? for details.
(Note: this is batch file syntax. If you want to use it directly on the command line, replace each %% with a single %)
You should be able to get the information for multiple URL files, without the need to nest two for loops. You can take advantage of FindStr's ability to search through multiple files directly.
batch-file:
#For /F "Tokens=1*Delims==" %%G In ('""%__AppDir__%findstr.exe" /IR "^URL=http" "*.url" 2>NUL"')Do #Echo %%H
cmd:
For /F "Tokens=1*Delims==" %G In ('""%__AppDir__%findstr.exe" /IR "^URL=http" "*.url" 2>NUL"')Do #Echo %H

I try to find a string "blabla" inside a file. If I find the string I replace it with "bloblo", if not do nothing. And I want to do this operation for all the files that I have in a folder.
When I apply the script on one file, it works well. When I use a for loop it doesn't work. it does not enter inside the for loop
Here is my script:
set "Var1=blabla"
set "Var2=bloblo"
FOR %%i IN (C:\Users\UserName\Desktop\TEST\*.txt) DO (
find /c "%Var1%" %%i
if %errorlevel% equ 1 goto notfound
call PathFile\FUNCTION_REPLACE.cmd %Var1% %Var2% %%i
:notfound
)
I use a script "Function_replace" to replace the values, here is the script:
SetLocal EnableExtensions DisableDelayedExpansion
Set "search=%~1"
Set "replace=%2"
Set "File=%3"
For /F "Tokens=1*Delims=]" %%A In ('Find /V /N ""^<"%File%"^&Break^>"%File%"'
)Do (Set "line=%%B"
SetLocal EnableDelayedExpansion
(If Not "%%B"=="" (Echo(!line:%search%=%replace%!)Else Echo()>>"%File%"
EndLocal)
I used to use directly the call of my replace function for each files of my folder. But it takes a long time to go inside each file. That's why I want to check before going inside each file, if the string exists or not (by using find /c).
Can you spot where is the issue coming from?
Based upon your latest edit, here's an example which sends only the files containing the string to be replaced, to the sub-function:
#Echo Off
SetLocal EnableExtensions DisableDelayedExpansion
Set "search=%~1"
Set "replace=%~2"
For /F Delims^=^ EOL^= %%A In ('FindStr /LIMP "%search%" *.*')Do Call :Sub "%%A"
GoTo :EOF
:Sub
Set "File=%~1"
For /F "Tokens=1*Delims=]" %%A In ('Find /V /N ""^<"%File%"^&Break^>"%File%"'
)Do (Set "line=%%B"
SetLocal EnableDelayedExpansion
(If Not "%%B"=="" (Echo(!line:%search%=%replace%!)Else Echo()>>"%File%"
EndLocal)
Please note that the FindStr command uses only example options, whilst the /M option is important to this solution you should check the output from FindStr /? to determine which of the others you would consider the most appropriate.
Why not simply list all files that has the string and exclude the files that don't? That seems like a more obvious plan to me:
#echo off
set "search=blabla"
for /f "delims=" %%i in ('findstr /m %search% "%USERPROFILE%\Desktop\TEST\*.txt"') do (
echo found "%search%" in "%%~fi"
)
If you want to still show files that does not contain the path, then #stephan already posted a comment on how to, no need for me to repeat.
I am creating a script that will get the computer version and serial number, turn it into variables, and then combine them together to create the new hostname.
However, the WMIC command for the serial number returns "T300"-"FDHGFJ "
Running just the serial number WMIC alone (without the does not "wmic csproduct get version") does not include the extra spaces.
I've tried looping it around one more time as other posts suggest but no luck.
Below is the full code.
#ECHO ON
PUSHD "%~dp0"
setlocal EnableDelayedExpansion
for /f "usebackq skip=1 tokens=*" %%i in (`wmic bios get serialnumber ^| findstr /r /v "^$"`) do set "serialn=%%i"
for /f "usebackq skip=1 tokens=2 delims= " %%a in (`wmic csproduct get version ^| findstr /r /v "^$"`) do set "modeln=%%a"
ECHO "%modeln%"-"%serialn%" >>test.txt
POPD
exit
I want the final result to be "T300"-"FDHGFJ" as it might get implemented into a task sequence.
You can try a bit of a hack by setting the variable only if not defined. I removed "tokens=*" and "delims=" as that will get the entire line. We then just do substitution on whitespace.
#echo off
set serialn=
set modeln=
for /f "usebackq skip=1" %%i in (`wmic bios get serialnumber`) do if not defined serialn set "serialn=%%i"
for /f "usebackq skip=1" %%a in (`wmic csproduct get version`) do if not defined modeln set "modeln=%%a"
echo "%modeln: =%"-"%serialn: =%">>test.txt
Note the output of second string on my device wmic csproduct get version has only one value and therefore I had to change the string, if yours really has 2 tokens then you should use your original string:
for /f "usebackq skip=1 tokens=2" %%a in (`wmic csproduct get version`) do if not defined modeln set "modeln=%%a"
The wmic command with its get verb might pad the returned data by trailing SPACEs, which I assume you want to have removed without removing SPACEs in the returned values themselves.
To achieve this you need to change the output format by adding the VALUE option, like this:
#echo off
setlocal EnableDelayedExpansion
cd /D "%~dp0."
for /F "tokens=1* delims==" %%I in ('wmic BIOS get SerialNumber /VALUE') do for /F "delims=" %%K in ("%%J") do set "serialn=%%K"
for /F "tokens=1* delims==" %%I in ('wmic CSProduct get Version /VALUE') do for /F "delims=" %%K in ("%%J") do set "modeln=%%K"
>> "test.txt" echo "%modeln%"-"%serialn%"
endlocal
exit /B
In addition I changed the following:
I placed another for /F loop inside of the one that parses the wmic output in order to avoid Unicode-to-ASCII/ANSI conversion artefacts by for /F, like orphaned carriage-return characters;
I replaced the pushd/popd pair by cd /D, because setlocal/endlocal already localises the environment, including the current working directory;
I added an explicit endlocal just to explicitly end the environment localisation (although this would be done upon termination of the batch script anyway);
I replaced exit by exit /B in order to only quit the batch file but not the parent cmd instance;
I put the redirection portion >> "test.txt" in front of the echo command in order to avoid the trailing space between the last closing " and >> (in your code) to be returned too;
As my initial comment regarding using /Value has already been implemented into an answer, this one expands upon using the wmic CSV format:
#Echo Off
SetLocal DisableDelayedExpansion
Set "DWM=%__AppDir__%wbem"
Rem Fixes 'Invalid XSL format (or) file name' errors in some Windows versions.
Set "CSV="
For /F "Delims=" %%A In ('"Dir /B/S/A-D "%DWM%\csv.xsl" 2>Nul"'
)Do If Not Defined CSV Set "CSV=%%A"
If Not Defined CSV Exit /B
Set "Serial#=Null"
For /F "Skip=2Tokens=1*Delims=," %%A In (
'""%DWM%\wmic.exe" BIOS Get SerialNumber /Format:"%CSV%" 2>Nul"'
)Do For /F Tokens^=* %%C In ("%%~B")Do Set "Serial#=%%~C"
Set "Model#=Null"
For /F "Skip=2Tokens=1*Delims=," %%A In (
'""%DWM%\wmic.exe" CSProduct Get Version /Format:"%CSV%" 2>Nul"'
)Do For /F Tokens^=* %%C In ("%%~B")Do Set "Model#=%%~C"
Echo "%Model#%"-"%Serial#%">>"test.txt"
Pause
I have a long test.properties file that contains the following at the very top:
property1=cheese
property2=apple
property3=bread
# many more properties
I can read those properties from the command line by changing the working directory to the one containing test.properties and running the following command:
> FOR /F "tokens=1,2 delims==" %A IN (test.properties) DO
IF "%A"=="property1" SET firstitem=%B
> FOR /F "tokens=1,2 delims==" %A IN (test.properties) DO
IF "%A"=="property2" SET seconditem=%B
> echo %firstitem%
cheese
> echo %seconditem%
apple
However, when I try to put this code in a batch file stored in the same directory, it fails and I cannot work out why:
FOR /F "tokens=1,2 delims==" %A IN ("%~dp0\test.properties") DO
(IF "%A"=="property1" SET firstitem=%B)
FOR /F "tokens=1,2 delims==" %A IN ("%~dp0\test.properties") DO
(IF "%A"=="property2" SET seconditem=%B)
Running the batch file from the command line gives me this:
> "C:\folder\testbatch.bat"
~dp0\test.properties") DO IF "B was unexpected at this time.
What can I do to read the properties using the batch file, so that they are stored in variables that can be used in the rest of the script?
EDIT: Problem solved; working code below.
FOR /F "usebackq tokens=1,2 delims==" %%A IN ("%~dp0\test.properties") DO
(IF "%%A"=="property1" SET firstitem=%%B)
FOR /F "usebackq tokens=1,2 delims==" %%A IN ("%~dp0\test.properties") DO
(IF "%%A"=="property2" SET seconditem=%%B)
There's two problems here:
In the batch file version you need two percent signs for the iterator variables.
In the batch file version you erroneously put quotes around the file name, causing the string itself to be tokenized, not the contents of the file specified by the string. Update: #Stephan correctly noted the use of the usebackq modifier for a more general solution. But since you're talking about "batch file stored in the same directory", you might as well drop the path prefix %~dp0 altogether.
Corrected version:
#ECHO OFF
FOR /F "tokens=1,2 delims==" %%A IN (test.properties) DO (
IF "%%A"=="property1" SET firstitem=%%B
)
FOR /F "tokens=1,2 delims==" %%A IN (test.properties) DO (
IF "%%A"=="property2" SET seconditem=%%B
)
ECHO %firstitem%
ECHO %seconditem%
Returns:
cheese
apple
"What can I do to read the properties using the batch file, so that
they are stored in variables that can be used in the rest of the
script?"
That is surprisingly easy in your case if you are willing to use the strings from the file:
FOR /F "usebackq tokens=*" %%A IN ("%~dp0\test.properties") DO set %%A
echo property2 is %property2%
Note: in case, your path or filename contains spaces, you need the quotes. Tell for not to treat it as a string with usebackq
I'm trying to get the revision number from a svn update command output. In the file tmpFile.txt I've got the string At revision 58998.
I've run the following command:
findstr /r "\<[0-9][0-9]*\>" "tmpFile.txt"
and I've got
At revision 58998.
Also, running with
findstr /r /o "\<[0-9][0-9]*\>" "tmpFile.txt"
I get
0:At revision 58998.
What's going on and how can I get only the number?
FINDSTR prints out the entire line that matches. It is not able to extract just the matching portion of the line.
You can use FOR /F to parse the output and get just the number.
for /f "tokens=3 delims=. " %%A in (
'findstr /rc:"At revision [0-9][0-9]*\." "tmpFile.txt"'
) do echo %%A
Not a findstr solution, but it works :)
setlocal enabledelayedexpansion
for /f "tokens=3" %%a in (tmpFile.txt) do (
set num=%%a
set num=!num:.=!
)
echo !num!
This will also remove the . from the end.
If your not bothered about the . use
for /f "tokens=3" %%a in (tmpFile.txt) do echo %%a
or for cmd line (no batch)
for /f "tokens=3" %a in (tmpFile.txt) do echo %a
This DOS batch script is stripping out the blank lines and not showing the blank lines in the file even though I am using the TYPE.exe command to convert the file to make sure the file is ASCII so that the FIND command is compatible with the file. Can anyone tell me how to make this script include blank lines?
#ECHO off
FOR /F "USEBACKQ tokens=*" %%A IN (`TYPE.exe "build.properties" ^| FIND.exe /V ""`) DO (
ECHO --%%A--
)
pause
That is the designed behavior of FOR /F - it never returns blank lines. The work around is to use FIND or FINDSTR to prefix the line with the line number. If you can guarantee no lines start with the line number delimiter, then you simply set the appropriate delimiter and keep tokens 1* but use only the 2nd token.
::preserve blank lines using FIND, assume no line starts with ]
::long lines are truncated
for /f "tokens=1* delims=]" %%A in ('type "file.txt" ^| find /n /v ""') do echo %%B
::preserve blank lines using FINDSTR, assume no line starts with :
::long lines > 8191 bytes are lost
for /f "tokens=1* delims=:" %%A in ('type "file.txt" ^| findstr /n "^"') do echo %%B
::FINDSTR variant that preserves long lines
type "file.txt" > "file.txt.tmp"
for /f "tokens=1* delims=:" %%A in ('findstr /n "^" "file.txt.tmp"') do echo %%B
del "file.txt.tmp"
I prefer FINDSTR - it is more reliable. For example, FIND can truncate long lines - FINDSTR does not as long as it reads directly from a file. FINDSTR does drop long lines when reading from stdin via pipe or redirection.
If the file may contain lines that start with the delimiter, then you need to preserve the entire line with the line number prefix, and then use search and replace to remove the line prefix. You probably want delayed expansion off when transferring the %%A to an environment variable, otherwise any ! will be corrupted. But later within the loop you need delayed expansion to do the search and replace.
::preserve blank lines using FIND, even if a line may start with ]
::long lines are truncated
for /f "delims=" %%A in ('type "file.txt" ^| find /n /v ""') do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*]=!"
echo(!ln!
endlocal
)
::preserve blank lines using FINDSTR, even if a line may start with :
::long lines >8191 bytes are truncated
for /f "delims=*" %%A in ('type "file.txt" ^| findstr /n "^"') do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*:=!"
echo(!ln!
endlocal
)
::FINDSTR variant that preserves long lines
type "file.txt" >"file.txt.tmp"
for /f "delims=*" %%A in ('findstr /n "^" "file.txt.tmp"') do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*:=!"
echo(!ln!
endlocal
)
del "file.txt.tmp"
If you don't need to worry about converting the file to ASCII, then it is more efficient to drop the pipe and let FIND or FINDSTR open the file specified as an argument, or via redirection.
There is another work around that completely bypasses FOR /F during the read process. It looks odd, but it is more efficient. There are no restrictions with using delayed expansion, but unfortunately it has other limitations.
1) lines must be terminated by <CR><LF> (this will not be a problem if you do the TYPE file conversion)
2) lines must be <= 1021 bytes long (disregarding the <CR><LF>)
3) any trailing control characters are stripped from each line.
4) it must read from a file - you can't use a pipe. So in your case you will need to use a temp file to do your to ASCII conversion.
setlocal enableDelayedExpansion
type "file.txt">"file.txt.tmp"
for /f %%N in ('find /c /v "" ^<"file.txt.tmp"') do set cnt=%%N
<"file.txt.tmp" (
for /l %%N in (1 1 %cnt%) do(
set "ln="
set /p "ln="
echo(!ln!
)
)
del "file.txt.tmp"
I wrote a very simple program that may serve as replacement for FIND and FINDSTR commands when they are used for this purpose. My program is called PIPE.COM and it just insert a blank space in empty lines, so all the lines may be directly processed by FOR command with no further adjustments (as long as the inserted space don't cares). Here it is:
#ECHO off
if not exist pipe.com call :DefinePipe
FOR /F "USEBACKQ delims=" %%A IN (`pipe ^< "build.properties"`) DO (
ECHO(--%%A--
)
pause
goto :EOF
:DefinePipe
setlocal DisableDelayedExpansion
set pipe=´)€ì!Í!ŠÐŠà€Ä!€ü.t2€ü+u!:æu8²A€ê!´#€ì!Í!².€ê!´#€ì!Í!²+€ê!´#€ì!Í!Šò€Æ!´,€ì!Í!"Àu°´LÍ!ëÒ
setlocal EnableDelayedExpansion
echo !pipe!>pipe.com
exit /B
EDIT: Addendum as answer to new comment
The code at :DefinePipe subroutine create a 88 bytes program called pipe.com, that basically do a process equivalent to this pseudo-Batch code:
set "space= "
set line=
:nextChar
rem Read just ONE character
set /PC char=
if %char% neq %NewLine% (
rem Join new char to current line
set line=%line%%char%
) else (
rem End of line detected
if defined line (
rem Show current line
echo %line%
set line=
) else (
rem Empty line: change it by one space
echo %space%
)
)
goto nextChar
This way, empty lines in the input file are changed by lines with one space, so FOR /F command not longer omit they. This works "as long as the inserted space don't cares" as I said in my answer.
Note that the pipe.com program does not work in 64-bits Windows versions.

Output lines including blank lines
Here's a method I developed for my own use.
Save the code as a batch file say, SHOWALL.BAT and pass the source file as a command line parameter.
Output can be redirected or piped.
#echo off
for /f "tokens=1,* delims=]" %%a in ('find /n /v "" ^< "%~1"') do echo.%%ba
exit /b
EXAMPLES:
showall source.txt
showall source.txt >destination.txt
showall source.txt | FIND "string"
An oddity is the inclusion of the '^<' (redirection) as opposed to just doing the following:
for /f "tokens=1,* delims=]" %%a in ('find /n /v "" "%~1"') do echo.%%ba
By omitting the redirection, a leading blank line is output.
Thanks to dbenham, this works, although it is slightly different than his suggestion:
::preserve blank lines using FIND, no limitations
for /f "USEBACKQ delims=" %%A in (`type "file.properties" ^| find /V /N ""`) do (
set "ln=%%A"
setlocal enableDelayedExpansion
set "ln=!ln:*]=!"
echo(!ln!
endlocal
)
As mentioned in this answer to the above question, it doesn't seem that lines are skipped by default using for /f in (at least) Windows XP (Community - Please update this answer by testing the below batch commands on your version & service pack of Windows).
EDIT: Per Jeb's comment below, it seems that the ping command, in at least Windows XP, is
causing for /f to produce <CR>'s instead of blank lines (If someone knows specifically why, would
appreciate it if they could update this answer or comment).
As a workaround, it seems that the second default delimited token (<space> / %%b in the example)
returns as blank, which worked for my situation of eliminating the blank lines by way of an "parent"
if conditional on the second token at the start of the for /f, like this:
for /f "tokens=1,2*" %%a in ('ping -n 1 google.com') do (
if not "x%%b"=="x" (
{do things with non-blank lines}
)
)
Using the below code:
#echo off
systeminfo | findstr /b /c:"OS Name" /c:"OS Version"
echo.&echo.
ping -n 1 google.com
echo.&echo.
for /f %%a in ('ping -n 1 google.com') do ( echo "%%a" )
echo.&echo.&echo --------------&echo.&echo.
find /?
echo.&echo.
for /f %%a in ('find /?') do ( echo "%%a" )
echo.&echo.
pause
.... the following is what I see on Windows XP, Windows 7 and Windows 2008, being the only three versions & service packs of Windows I have ready access to:
