I have txt files that contain several lines and I need to create a log out of them to store in a log the following information:
File Name
Last modified
Count of lines containing the word "valid"
I've put together a .bat file but it splits the output in two lines.
type nul > FilesReceived.txt & for %f in (*.log) do (
find /c "valid" %f & echo(%~tf)>> LogsReceived.txt
)
With type nul I clear the contents of the FilesReceived.txt file. Then I loop through the files of type log.
Then I count lines that contain the word valid with find /c and I also echo the last modified time stamp.
However the output looks like:
---------- transaction_20160505_1005A.log: 6492
10/06/2016 04:37 p.m.
I don't know what's generating those dashes. Ultimately I'd like to have one line per log file as follows:
transaction_20012B.log: 6492 10/06/2016 04:37 p.m.
Hope you guys can help me.
Thanks,
Bruce
find prints the dashes if it processes a file. It doesn't, when processing from STDIN (type file.ext /c |find "string" prints the count only).
There is a trick to write without linefeed: <nul set /p"=Hello"
If you can live with another order, it's quite easy to assemble it::
#echo off
for %%f in (*.bat) do (
<nul set /p "=%%f %%~tf "
type %%f|find /c "echo"
)
If you want to keep your order it's a little bit more complicated: you can't force find to write without linefeed, so you have to use a trick (another for):
#echo off
(for %%f in (*.txt) do (
<nul set /p "=%%f: "
for /f %%i in ('type %%f^|find /c "valid"') do (<nul set /p "=%%i ")
echo %%~tf
))>LogsReceived.txt
You may get the output of find command via another for and put it at any place you wish:
#echo off
(for %%f in (*.log) do (
for /F %%c in ('find /c "valid" ^< %%f') do echo %%f: %%c %%~tf
)) > LogsReceived.txt

I am a serious newbie at creating batch files and am hoping someone can help me. One of our staff receives zipped pdf docs by email, which she copies to a folder on her desktop. Within that folder, I would like for her to run a batch script that will
A. Unzip the zipped contents into a network directory, i.e. \server\contracts
Under this directory, the process will create folders for each group of contracts, i.e. \server\contracts\Masterson (The name of this will be same as zipped file name).
B. Then the batch process should copy a select few of the pdf documents into a network directory based on the filename. Each file contains a number, which will go in the following manner: Masterson + 1.pdf >> \server\contracts\Item1 and \server\contracts\Item2, etc. Masterson + 1.pdf will go into \server\contracts\Item1 without a folder name, as will Paisley + 1 certificate.pdf and Johnsonville + 1 document.pdf.
The problem is that the companies do not follow instructions and the number can be at the beginning, middle, or end of the file name. Also, unfortunately, there are spaces in the name of the zipped file and the pdf documents. Currently, we are only copying 4 filenames into separate directories for other people to review and validate.
Below is what I did so far looking around this site:

Of course this doesn't work. Please help!
Well - bravo for the attempt! And so close...
Let's take the first part
for /R "delims=\\server\contracts\RECEIVED 2017-18 APPLICATION" %%I in ("*.zip") do (
"%ProgramFiles(x86)%\7-Zip\7z.exe" x -y -o"%%~dpnI" "%%~fI"
)
What's wrong here is that the delims clause is only usable in for /f. for /r always delivers the entire filename to the metavariable %%I.
On my system I use %server%\u for testing - u is a shared resource on the server assigned to U:\ on server.
for /R "\\%server%\u\contracts\RECEIVED 2017-18 APPLICATION" %%I IN ("*.zip") do (
"%ProgramFiles(x86)%\7-Zip\7z.exe" x -y -o"%%~dpnI" "%%~fI"
worked happily for me - delivering the extracted files to "u:\contracts\RECEIVED 2017-18 APPLICATION"
The second part of your code is examining "C:\Users\eartha.kitt\Desktop\Test" not "\%server%\u\contracts\RECEIVED 2017-18 APPLICATION" - very sensibly assigned to a variablename for easy adjustment.
Here's my modified code:

goto:Loop
First, I set up terminatefilename so that creating this file will terminate the batch (it's an infinite loop by design in your code)
Next, I overrode your inputfolder name to suit my system.
Then the output directories. I adjusted their names to suit my system. Note that batch is largely case-insensitive, so setting Output8A and Output8a is setting the same variable. The only time that batch commands are case-sensitive is the metavariable (loop-control variable) in a for statement.
Then I inserted a line to create the destination directories. This uses a set command to list the variables starting output in the format Output1=\\%server%\u\contracts\ITEM 1 17-18 CERTS (where server will have been resolved). The command reads the output of the set command, uses = as the delimiter and assigns output1 to %%b and \\%server%\u\contracts\ITEM 1 17-18 CERTS to %%c. We want to make sure the directory %%c exists, so we make it with an md command and ignore complaints that it already exists with 2>nul.
Next the for/f. for /f reads each line of (thisfilename) or ("this literal value") or ('the output of this command') but when you need to read a from a file whose name must be double-quoted beacuse it contains spaces, then the syntax is for /f "usebackq"... (idontknow) or ("this filename containing spaces") or ('ive no idea whatever') or (`the output of this command`)
So there's no need to use usebackq -- in fact, it's counterproductive.
The delims=| is optional and could be replaced by delims= as the output of a dir command will never contain | (illegal in a file or directoryname). You do need the delims clause however, as the default delimiters include Space and the default tokens is 1 so only the first string of each line output up to the first space will be assigned to %%a.
Hmm - you've remmed-out a for/r. Sadly, the target directory in the for /r can't be a metavariable.
Next, I've cleared a copied flag saying "so far, this file has not been copied"
Next, set fichier to the name-part only of the filename. Since you are using .pdf as a filter, each name output by the for/f will be a full-filename, ending in .pdf
Next, almost-correct with the battery of if statements. The /i makes the comparison case-insensitive so that it will cope with both 8a and 8A. The strings on both sides of the == must be identical to pass the == test, so you need a 3-character string in the 8 tests.
You've evidently been experimenting with the copy command and trying to feed it with appropriate strings. %%~a strips %%a of any enclosing quotes. %%a won't have enclosing quotes - just the fullfilename, so this does nothing in this instance. %InputFolder%\~%%a concatenates the values from InputFolder,"\~" and %%a - which means "%inputfolder%\~%inputfolder%\filenameandextension of %%a". The last two would be resolved to the same, bar the ~.
Since the entire filename is contained in %%a, all that's needed for the sourcefile is "%%a" - quoted as it will probably contain spaces.
Well - the destination directory (we've already established it with the for /f...%%b) can also contain spaces, so it needs to be quoted, too.
I've then set the flag copied to Y if the line took effect. Actually, it can be set to any non-empty value as the whole object is to interpret whether or not it exists with an if defined statement to bypass any later attempts to copy the same file (remember - copied is cleared for each file)
Now - the second option. This is actually a more powerful detector of the required target strings than is the substring version, and will detect the target string anywhere in the filename.
If you echo the name-part only of the file %%~na into a findstr, then set to findstr to look for the /L literal string /i case-insensitive c:"some literal string" and output ny matches found to nowhere (>nul) then findstr will set errorlevel to 0 if found and 1 otherwise. (the /L is superfluous here, I use it habitually to remind me I'm working with literal strings, not regular expressions)
If errorlevel n will be true if errorlevel is currently n or greater than n, so if the string is found, we do the copy and set the copied flag as before.
I reversed the order of tests because it was easier for me to do using the editor I use.
Now - there's a downside to this approach. It's a double-edged sword. Since the target string is detected wherever it appears in the filename, whatever whatever 10 something something.pdf will pass the test for 1 because Space1 appears in its name.
When the loop has finished, use timeout to wait, redirecting the output to nul to make it pipe down. Note that your delay was inside the for loop - so it would have waited 6 seconds after processing each file, not 6 seconds after processing an entire batch.
Finally, if you create terminatefilename from anothe cmd instance, the batch will exit cleanly and kill terminatefilename for you. Much cleaner than control-c.
A last note: Since you are copying the file, not MOVEing it, it will still exist in the same place presumably after the 6 seconds has elapsed and will be endlessly copied and recopied. You'd probably need to make adjustments to achieve the desired result.
I've been working on a BAT file which will delete old files based on creation date. To do this I've generated a list of all files and paths, then a list of files names to be protected. FINDSTR is then used to remove these files from the list of files and paths.
This system works fine until I encounter a file with a dash (or so it seems!)
Here's an example:
cleaner_protect.txt contains:
New File.txt
New File - Copy.txt
cleaner_fullpath.txt contains:
P:\New File.txt
P:\New File - Copy.txt
P:\Old File.txt
I want to remove the New Files stored in cleaner_protect.txt from the cleaner_fullpath.txt, leaving the Old Files behind which I will later delete (not up to that bit yet lol). Here is my code so far:
:: Remove protected files from list to be deleted (fullpath)
:RemoveFile
:: load string into variable
set /p target= <cleaner_protect.txt
:: remove protected file from full path list
echo -----------------------------
echo Searching for: "%target%"
echo -----------------------------
pause
findstr /v ".\<%target%\>." cleaner_fullpath.txt > cleaner_temp.txt
echo -----------------------------
type cleaner_temp.txt
echo -----------------------------
pause
del cleaner_fullpath.txt
ren cleaner_temp.txt cleaner_fullpath.txt
:: Count remaining lines in list
Set target=cleaner_protect.txt
Set /a lines=0
For /f %%j in ('Find "" /v /c ^< %target%') Do Set /a lines=%%j
Echo %target% has %lines% lines.
pause
:: Loop until completed
IF %lines% GTR 0 (
:: Remove line from protected list
more +1 cleaner_protect.txt > cleaner_temp.txt
del cleaner_protect.txt
ren cleaner_temp.txt cleaner_protect.txt
set /a lines-=1
GOTO :RemoveFile
)
Pauses and echos are for debugging purposes... I want this to run almost invisibly.
Can anyone shed some light on this? I need this code to repeatedly go through a dropbox and delete old files which may be in various levels of structure.
Maybe this simple line does all you want:
findstr /E /V /G:cleaner_protect.txt cleaner_fullpath.txt > cleaner_temp.txt
Sample output:
P:\Old File.txt
I would do it as follows:
#echo off
setlocal EnableExtensions DisableDelayedExpansion
rem /* Prepend each line of `cleaner_protect.txt` with `\\`, remove a trailing space,
rem if applicable, and write result to `cleaner_temp.txt`: */
> "cleaner_temp.txt" (
for /F "usebackq delims= eol=|" %%E in ("cleaner_protect.txt") do (
set "ITEM=\\%%E|"
setlocal EnableDelayedExpansion
echo !ITEM: ^|=!
endlocal
)
)
rem /* Search `cleaner_fullpath.txt` for lines that do not end in any of the lines of
rem `cleaner_temp.txt` and process the returned items only: */
for /F "delims= eol=|" %%F in ('
findstr /V /I /E /L /G:"cleaner_temp.txt" "cleaner_fullpath.txt"
') do (
ECHO del "%%F"
)
rem // Clean up temporary file `cleaner_temp.txt`:
del "cleaner_temp.txt"
endlocal
exit /B
After having tested the script, remove the upper-case ECHO command.
Supposing cleaner_protect.txt contains this:
New File.txt
New File - Copy.txt
The temporary file cleaner_temp.txt is going to contain this:
\\New File.txt
\\New File - Copy.txt
So having the text file cleaner_fullpath.txt:
P:\New File.txt
P:\New File - Copy.txt
P:\Old File.txt
Only the following items are processed:
P:\Old File.txt
The leading \\ is taken as one literal \ by findstr (as it uses the \ as an escape character).
The prefix \\ is implemented in order to cover also the following situations:
Let us assume cleaner_protect.txt holds this:
New File.txt
And cleaner_fullpath.txt holds this:
P:\New File.txt
P:\Very New File.txt
Without the prefix, P:\Very New File.txt would also match New File.txt at the end, hence it would not become deleted erroneously.
Then let us assume cleaner_protect.txt holds this:
.File.txt
And cleaner_fullpath.txt holds this:
P:\.File.txt
P:\Other.File.txt
With a \ prefix, P:\Other.File.txt would also match \.File.txt at the end, because . is a meta character to findstr (even though literal search strings are defined by /L, but escaping like \. still applies and results in a literal .), hence it would also not become deleted erroneously. However, with a \\ prefix, escaping applies to the second \, so a literal \ is the result; the . does not need to be escaped with the /L option.

You have specified an invalid pipe | find. You cannot pipe (a) text file(s) into a command.
Either provide the file(s) as argument(s) to find, or use redirection (this works for a single file only but not for multiple ones nor */? patterns though).
You are using for /f not correctly.
It looks as if you wanted to parse the output of find. To accomplish that, but you must enclose the command within single-quotes '. Type for /? and see the help text for more details.
The following line of code should work:
for /f "tokens=*" %%a in ('find "192.168.1" *.txt') do (
To get current date and time, I strongly recommend to read variables %DATE% and %TIME% once only and within a single line! Otherwise you might run into problems, especially concerning the fractional seconds, which might not be equal between consecutive expansions.
To ensure %HOUR% to have two digits, you simply need to use set HOUR=0%HOUR% then set HOUR=%HOUR:~-2%.
Since a one-digit %HOUR% is prefixed by a space here, you can have it even simpler (thanks for your comment, #Stephan!) by just replacing the space by a zero: set HOUR=%HOUR: =0%.
I have managed to output a query from:
REG Query "HKLM\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall " /F "LanSchool Teacher" /s > %temp%\lanschool.txt
%temp%\lanschool.txt
FOR /F "delims=\" %%a in ('find "%temp%\lanschool.txt) DO (
echo token8=%%h
)
pause
However now I have the text file, and it has numerous lines of output in it.
Is it possible to do a:
FOR /F "delims=\" %%a in ('find "%temp%\lanschool.txt) DO (
echo token8=%%h
)
But I only want this to run on one line, and that line may change but the only line of that code that I want it to run on, only has one difference compared to another line of code (and that difference is the part of the code that I am trying to get into the %%h variable).
The output is this:
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\Teacher
DisplayName REG_SZ LanSchool Teacher
HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{89F475EE-2075-4F35-A37D-30C69916EE64}
DisplayName REG_SZ LanSchool Teacher
End of search: 2 match(es) found.
I would like to get the {89F475EE-2075-4F35-A37D-30C69916EE64} part to be token %%h however at the moment as you can see there is 2 REG Keys being output, and the only difference is the part that I want to use, and I can't always guarantee that there will only be 2 REG Keys output.
Sorry if I was all over the place explaining this, let me know if you would like anything clarified.
This line should fix it. It uses find.exe to search for the character { and if it is not found then the file will not be created, so you can branch on that.

Any ideas how to echo or type the last 10 lines of a txt file?
I'm running a server change log script to prompt admins to state what they're doing, so we can track changes. I'm trying to get the script to show the last 10 entries or so to give an idea of what's been happening recently. I've found a script that deals with the last line, as shown below, but can't figure out what to change in it to display the last 10 lines.
Script:
#echo off
setLocal EnableDelayedExpansion
for /f "tokens=* delims= " %%a in (c:\log09.txt) do (
set var=%%a
)
echo !var!
Example of log file:
06/02/2009, 12:22,Remote=Workstation-9,Local=,
mdb,bouncing box after updates,CAS-08754,
=================
07/02/2009, 2:38,Remote=,Local=SERVER1,

=================
07/02/2009, 3:09,Remote=,Local=SERVER1,
mdb,audit of server,CAS-08776,
Any thoughts?
The script works great, just need it to pipe more lines to the screen.
Hopefully this will save Joel's eyes :)

This answer combines the best features of already existing answers, and adds a few twists.
The solution is a simple batch implementation of the tail command.
The first argument is the file name (possibly with path information - be sure to enclose in quotes if any portion of path contains spaces or other problematic characters).
The second argument is the number of lines to print.
Finally any of the standard MORE options can be appended: /E /C /P /S /Tn. (See MORE /? for more information).
Additionally the /N (no pause) option can be specified to cause the output to be printed continuosly without pausing.
The solution first uses FIND to quickly count the number of lines. The file is passed in via redirected input instead of using a filename argument in order to eliminate the printout of the filename in the FIND output.
The number of lines to skip is computed with SET /A, but then it resets the number to 0 if it is less than 0.
Finally uses MORE to print out the desired lines after skipping the unwanted lines. MORE will pause after each screen's worth of lines unless the output is redirected to a file or piped to another command. The /N option avoids the pauses by piping the MORE output to FINDSTR with a regex that matches all lines. It is important to use FINDSTR instead of FIND because FIND can truncate long lines.

You should probably just find a good implementation of tail. But if you really really insist on using CMD batch files and want to run on any NT machine unmolested, this will work:
#echo off
setLocal EnableDelayedExpansion
for /f "tokens=* delims= " %%a in (c:\tmp\foo.txt) do (
set var9=!var8!
set var8=!var7!
set var7=!var6!
set var6=!var5!
set var5=!var4!
set var4=!var3!
set var3=!var2!
set var2=!var1!
set var1=!var!
set var=%%a
)
echo !var9!
echo !var8!
echo !var7!
echo !var6!
echo !var5!
echo !var4!
echo !var3!
echo !var2!
echo !var1!
echo !var!
There are several windows implementations of the tail command. It should be exactly what you want.
This one sounds particularly good:
http://malektips.com/xp_dos_0001.html
They range from real-time monitoring to the last x lines of the file.
Edit: I noticed that the included link is to a package It should work, but here are some more versions:

If file is too large it can take too long to get count of lines
another way is to use find and pass it a nowhere string
$find /v /c "%%$%!" yourtextfile.txt
this would result an output like this
$---------- yourtextfile.txt: 140
then you can parse output using for like this
$for /f "tokens=3" %i in ('find /v /c "%%$%!" tt.txt') do set countoflines=%i
then you can substract ten lines from the total lines
After trying all of the answers I found on this page none of them worked on my file with 15539 lines.
However I found the answer here to work great. Copied into this post for convenience.
#echo off
for /f %%i in ('find /v /c "" ^< C:\path\to\textfile.txt') do set /a lines=%%i
set /a startLine=%lines% - 10
more /e +%startLine% C:\path\to\textfile.txt
This code will print the last 10 lines in the "C:\path\to\textfile.txt" file.

using a single powershell command:
powershell -nologo "& "Get-Content -Path c:\logFile.log -Tail 10"
applies to powershell 3.0 and newer
I agree with "You should use TAIL" answer. But it does not come by default on Windows. I suggest you download the "Windows 2003 Resource Kit" It works on XP/W2003 and more.
If you don't want to install on your server, you can install the resource kit on another machine and copy only TAIL.EXE to your server. Usage is sooooo much easier.
C:\> TAIL -10 myfile.txt
Here's a utility written in pure batch that can show a lines of file within a given range.To show the last lines use (here the script is named tailhead.bat):
call tailhead.bat -file "file.txt" -begin -10
Any ideas how to echo or type the last
10 lines of a txt file?
The following 3-liner script will list the last n lines from input file. n and file name/path are passed as input arguments.
# Script last.txt
var str file, content ; var int n, count
cat $file > $content ; set count = { len -e $content } - $n
stex -e ("["+makestr(int($count))) $content
The script is in biterscripting. To use, download biterscripting from http://www.biterscripting.com , save this script as C:\Scripts\last.txt, start biterscripting, enter the following command.
script last.txt file("c:\log09.txt") n(10)
The above will list last 10 lines from file c:\log09.txt. To list last 20 lines from the same file, use the following command.
script last.txt file("c:\log09.txt") n(20)
To list last 30 lines from a different file C:\folder1\somefile.log, use the following command.
script last.txt file("C:\folder1\somefile.log") n(30)
I wrote the script in a fairly generic way, so it can be used in various ways. Feel free to translate into another scripting/batch language.
