I'm looking to find a solution to an issue I'm having trying to add an extension to the end of every line in a text file. I have a solution that works well, except it adds a space to the end after every line. Here's what I have:
#echo off
Set "_t1=PDF List.txt"
Set "_t3=.pdf"
PUSHD %_t0%
If EXIST tmp.txt del tmp.txt
For /F "usebackq delims=" %%A in ("%_t1%") do echo %%A%_t3% >>tmp.txt
del "%_t1%"
rename tmp.txt "%_t1%"
For %%A in (0 1 2) do Set _t%%A=
POPD
Remove the space from your echo command:
For /F "usebackq delims=" %%A in ("%_t1%") do echo %%A%_t3%>>tmp.txt

#echo off
echo File Extionsion To Create List?
SET /p Ext=Ext:
echo %Ext%
for /f "tokens=1 delims=." %%g in ('dir /b *.%Ext%') do echo %%g >> Names.txt
How do you remove the last dot and the file extension without accidentally removing other dots. For example 10.01320.pdf will become 10.01320.
Since your goal is to keep all the .'s in the file name just not the extension, you can simply use some Parameter Extensions. In the example of your goal, %%~ng will Expand %%g to a file Name without file extension or path.
#echo off
echo File Extionsion To Create List?
SET /p Ext=Ext:
echo %Ext%
for /f "tokens=1 delims=*" %%g in ('dir /b *.%Ext%') do echo %%~ng >> Names.txt
I am trying to write a batch script that reads 18th line from a .log file and outputs the same. The .log file name varies each time. abc_XXXX.log where xxxx are process IDs. Below is the code I am trying to run to achieve this.
:Test1
set "xprvar=" for /F "skip=17 delims=" %%p in (abc*.log) do (echo %%p& goto
break)
:break
pause
goto END
set var=anyCommand doesn't work. It just sets the var to the literal string.
The usage of afor /f is the right way, just the variable assignment works different:
for /F "skip=17 delims=" %%p in ('dir /b abc*.log') do ( set "xprvar=%%p"& goto break )
There is also an option using FindStr
#Echo Off
For /F "Tokens=1-2* Delims=:" %%A In ('FindStr/N "^" "abc_*.log" 2^>Nul'
) Do If %%B Equ 18 Echo %%A:%%C
Pause
The above example Echoes the <filename>:<18th line content>, but there's no reason in the appropriate situation why you couldn't change that to read:
#Echo Off
For /F "Tokens=1-2* Delims=:" %%A In ('FindStr/N "^" "abc_*.log" 2^>Nul'
) Do If %%B Equ 18 Set "xprvar=%%C"
If there is more than one matching filename in the directory, the variable would be set to the content in the last file parsed.
#ECHO Off
SETLOCAL
FOR %%f IN (abc*.log) DO (
SET "reported="
FOR /f "skip=17delims=" %%p IN (%%f) DO IF NOT DEFINED reported (
ECHO %%p
SET "reported=Y"
)
)
Assign each filename in turn to %%f.
For each filename found, clear the reported flag then read the file, skipping the first 17 lines. echo the 18th line and set the reported flag so that the remainder of the lines are not echoed.
This is my first posting so if the format is not as it supposed to be please excuse me for this. (Suggestions for
improvement are welcome.)
I am trying to create a batchfile that will read last lines from logfiles and copy them to a new file.
Until now I have found here a way to read the last line.
Code would be something like:
for /f %%i in ('find /v /c "" ^< someFile.txt') do set /a lines=%%i
set /a startLine=%lines% - 1
more /e +%startLine% someFile.txt > lastLines.txt
The above code works for one file at a time. What I need is to read the last line from all files in a known list and add this line to a new .csv file.
I have been using the following code for getting the 4th entry in the logfiles but it returns every line of every logfile:
for /f %%x in (%list%) do for /f "delims=.txt, tokens=4" %%i in (%%x.txt) do echo %%x, %%i >> output.csv
What I would need is a sort of combination of both but I don't know how to combine them and make the complete last line be copied to the .csv file.

#Magoo:
Thanx for your reaction.
In every logfile can be 1 to >100 lines with comma separated information. Something like:
"LOGON,6-1-2015,12:43:39,USERNAME,HOSTNAME,,,,192.168.209.242,00:21:5A:2E:64:5E"
The last code with the 4th entry was used to get a list of all accounts that had logged in to the computers. This code gave me a very large list of all logon/logoff events on all computerlogs I checked in %list%.
In %list$ I had all the names of logfiles I wanted to be checked. This returned all lines.
For a new batchfile I need only the last logon/logoff entry and I want the whole last line.
So I have a .txt file with the hostnames of all computers I need to examine.
This .txt file will be read line by line via the variable %list%.
From every logfile I need only the last line copied to an output file.

I just tried the solution offered by JosefZ. Unfortunately this does not work for me yet. No lastlines are copied to the resultfile. In the code I removed the extra entry for possible lastlines for there are no empty lines in the logs, I also added an entry for the hostname I want to be available in the result. JosefZ had the filename there:
#ECHO OFF >NUL
#SETLOCAL enableextensions disabledelayedexpansion
type nul>output.csv
set "list=_listing.txt"
for /F "tokens=*" %%x in ('type "%list%"') do (
set "host=%%~x"
for /F "tokens=*" %%G in ('type "%%~x"') do set "lastline=%%G"
call :lline
)
:endlocal
#ENDLOCAL
goto :eof
:lline
set "filename=.\logs\%filename:&=^&%.txt"
echo %host%,%lastline%>>output.csv
goto :eof
The resultfile shows only the hostnames. I'll puzzle some more with this but all tips are welcome!
===
Got it!!!
#ECHO OFF >NUL
#SETLOCAL enableextensions disabledelayedexpansion
type nul>output.csv
set "list=_listing.txt"
for /F "tokens=*" %%x in ('type "%list%"') do (
set filename= :: *empty previous filename*
set lastline= :: *empty previous lastline*
set "host=%%~x"
set "filename=.\logs\%host%.txt" :: *creating the filename from path+hostname+extention*
for /F "tokens=*" %%G in ('type "%filename%"') do set "lastline=%%G"
call :lline
)
:endlocal
#ENDLOCAL
goto :eof
:lline
echo %host%,%lastline%>>output.csv
goto :eof
Your approach with line numbering could fail if a file has more trailing empty lines. Fortunately for /F loop ignores (does not iterate) empty lines; let's put to use this feature: in the script used next practices:
disabledelayedexpansion to allow ! in file names
set "list=_listing.txt" where the _listing.txt contains list of file names (full path and extension .txt including), one file name on one line: got by dir /b /s *.txt>_listing.txt
type nul>files\output.csv to empty the output file (optional)
set "lastline=!!!file empty!!!" to initialize variable %lastline%; could be set "lastline=" as well
call :lline to process variables %filename% and %lastline%
set "filename=%filename:&=^&%" to allow & in file names
The script is as follows:
#ECHO OFF >NUL
#SETLOCAL enableextensions disabledelayedexpansion
type nul>files\output.csv
set "list=_listing.txt"
for /F "tokens=*" %%x in ('type "%list%"') do (
set "filename=%%~x"
set "lastline=!!!file empty!!!"
rem the whole line
for /F "tokens=*" %%G in ('type "%%~x"') do set "lastline=%%G"
rem the fourth token only
rem for /F "tokens=4" %%G in ('type "%%~x"') do set "lastline=%%G"
call :lline
)
:endlocal
#ENDLOCAL
goto :eof
:lline
set "filename=%filename:&=^&%"
echo %filename% %lastline%
rem >>files\output.csv
goto :eof
Sample _listing.txt file:
d:\bat\files\1exclam!ation.txt
d:\bat\files\2exc!lam!ation.txt
d:\bat\files\11per%cent.txt
d:\bat\files\12per%cent%.txt
d:\bat\files\17per%Gcent.txt
d:\bat\files\18per%%Gcent.txt
d:\bat\files\21ampers&nd.txt
d:\bat\files\22ampers&&nd.txt
Output:
d:\bat>lastlines

d:\bat\files\2exc!lam!ation.txt 6 15.01.2015 1:52:28.50 3250 16741

Honestly, all that ballast is for (possibly) trailing empty lines in files and for (possibly) ! and & in file names only; all could be done with
for /f %%x in (%list%) do for /f "skip=%startLine% tokens=4" %%i in (%%x) do echo %%x, %%i >> output.csv
You should use a simple FOR to iterate a list of values, not FOR /F.
Something like the following should work:
#echo off
setlocal enableDelayedExpansion
>>output.csv (
for %%F in (
"file1.log"
"file2.log"
"file3.log"
etc.
) do (
for /f %%A in ('find /v /c "" <%%F') do set /a skip=%%A-1
more +!skip! %%F
)
)
The quotes around the file names are there in case you get a name with spaces.
You could use your LIST variable if it looks something like
set LIST="file1.log" "file2.log" "file3.log" etc.
#echo off
setlocal enableDelayedExpansion
set LIST="file1.log" "file2.log" "file3.log" etc.
>>output.csv (
for %%F in (%LIST%) do (
for /f %%A in ('find /v /c "" <%%F') do set /a skip=%%A-1
more +!skip! %%F
)
)
If any of your file names contain the ! character, then you must toggle delayed expansion ON and OFF within your loop. Otherwise the delayed expansion will corrupt the names when %%F is expanded.
#echo off
setlocal disableDelayedExpansion
set LIST="file1.log" "file2.log" "file3.log" etc.
>>output.csv (
for %%F in (%LIST%) do (
for /f %%A in ('find /v /c "" <%%F') do set /a skip=%%A-1
setlocal enableDelayedExpansion
more +!skip! %%F
endlocal
)
)
I have a simply FOR /F loop which strips out all but one line of a text file:
for /f "skip=12 tokens=* delims= " %%f in (.\NonProcessed\*.txt) do (
> newfile.txt echo.%%f
goto :eof
)
But when I run, I get the result:
The system cannot find the file .\NonProcessed\*.txt
The for loop works fine if I enter a fully qualified path to the text file within the brackets, but it can't handle the relative link I have in there. I've been able to use the exact same relative link in another standard for loop in a different batch file running in the same directory without any issues. I can't understand why it won't work! Please help.
EDIT: For comments, code I'm using now is
for %%f in (.\NonProcessed\*.txt) do (
echo f is %%f
for /f "usebackq skip=12 tokens=* delims= " %%a in (%%f) do (
echo a is %%a
> %%f echo.%%a
goto :continue
)
:continue
sqlcmd stuff here
)
Sorry but for /f does not allow you to do that. And no, the problem is not the relative path to files but the wildcard.
According to documentation, you have the syntax case
for /F ["ParsingKeywords"] {%% | %}variable in (filenameset) do command [CommandLineOptions]
For this case, documentation states The Set argument specifies one or more file names. You can do
for /f %%a in (file1.txt file2.txt file3.txt) do ...
but wildcards are not allowed.
If you don't know the name of the file you want to process, your best option is to add an additional for command to first select the file
for %%a in (".\NonProcessed\*.txt"
) do for /f "usebackq skip=12 tokens=* delims= " %%f in ("%%~fa"
) do (
> newfile.txt echo(%%f
goto :eof
)
When executed, the goto command will cancel both for loops so you end with the same behaviour you expected from your original code.
edited to adapt code to comments
#echo off
set "folder=.\NonProcessed"
pushd "%folder%"
for /f "tokens=1,2,* delims=:" %%a in (
' findstr /n "^" *.txt ^| findstr /r /b /c:"[^:]*:13:" '
) do (
echo Overwrite file "%%a" with content "%%c"
>"%%a" echo(%%c
)
popd
Read all the files in the folder, numbering the lines. The output for the first findstr command will be
filename.txt:99:lineContents
This output is parsed to find the line 13, the resulting data is splitted using the colon as a separator, so we will end with the file name in %%a, the line number in %%b and the line content in %%c.
SET FILES_LIST=files_list.config
DIR /b .\NonProcessed\*.txt>!FILES_LIST!
for /f "skip=12 tokens=* delims= " %%f in (!FILES_LIST!) do (
> newfile.txt echo.%%f
goto :eof
)
IF EXIST "!FILES_LIST!" DEL "!FILES_LIST!"
I did not check how your's FOR works, just added my additions/corrections to it.... Hope it will work for you.
Best regards!
I am looking to find a batch or VBS solution to strip out lines in a program generated text file with the extension of .trs.
In every .trs file created there is a line that contains the word 'labour'. I need every line after the line that contains the word labour to be deleted.
The .trs files are all stored in c:\export
I have searched for this but some of the commands were well over my head. Could anyone be so kind as to offer me a cut and paste open of the whole batch file, please.
I believe this is the code you are looking for (in a batch file) to remove all of the lines above the word "labour". Let me know if modifications need to be made to the code (such as if there are more than one instance of "labour" in the file).
#echo OFF
setLocal EnableDelayedExpansion
cd C:\export
for /f "delims=" %%I in ('findstr /inc:"labour" "test.trs"') do (
set /A"line=%%I"
)
set count=0
for /f "delims=" %%A in (test.trs) do (
If !count! GEQ %line% goto ExitLoop
echo %%A >>temp.txt
set /A count+=1
echo !count!
)
:ExitLoop
type temp.txt > test.trs
del temp.txt
endlocal
OUTPUT:
test.trs (BEFORE changes)
this
is
a
labour
test
of
the
results
test.trs (AFTER changes)
this
is
a
Here is an alternate method to process every .trs file in "C:\export":
#echo off
if not exist "C:\export\*.trs" goto :EOF
if exist "C:\export\queue.tmp" del /q "C:\export\queue.tmp"
for /f "tokens=*" %%A in ('dir /b "C:\export\*.trs"') do (
for /f "tokens=1,2 delims=:" %%B in ('findstr /inc:"labour" "C:\export\%%A" ^| findstr /n .*') do if "%%B" equ "1" set LineNumber=%%C
for /f "tokens=1* delims=:" %%D in ('findstr /n .* "C:\export\%%A"') do if %%D lss %LineNumber% echo.%%E>>"C:\export\queue.tmp"
move /y "C:\export\queue.tmp" "C:\export\%%A">NUL
)
First, I do some error checking to avoid things that would break the script. Next, I pull a list of .trs files stored in C:\export, and loop through each file.
I use 'findstr /inc:"labour" "C:\export\%%A"' to get the line number where "labour" is found in the current file, then pipe it into 'findstr /n .*' to number the results in case more than one match is found.
I then use a for loop with "tokens=1,2 delims=:" to find the first result (if "%%B" equ "1") and store the line number (set LineNumber=%%C).
Next, I use 'findstr /n .* "C:\export\%%A"' to read every line of the file, "tokens=1* delims=:" to separate out the line numbers again, then copy all the data to a temp file until %LineNumber% has been reached. This method of reading the file (using findstr and numbering the lines) also ensures that no blank lines will be skipped by the for loop.
Finally, I replace the original file with the temp file, then loop through to the next file.
I tried to keep the above code as slimmed down as possible. Here is the same script with formatting, comments, visual feedback, and user-definable variables:
#echo off
::Set user-defined Variables
set FilePath=C:\export
set FileType=*.trs
set Keyword=labour
::Check for files to process and exit if none are found
if not exist "%FilePath%\%FileType%" echo Error. No files to process.&goto :EOF
::Delete temp file if one already exists
if exist "%FilePath%\queue.tmp" del /q "%FilePath%\queue.tmp"
::List all files in the above specified destination, then process them one at a time
for /f "tokens=*" %%A in ('dir /b "%FilePath%\%FileType%"') do (
::Echo the text without a line feed (so that "Done" ends up on the same line)
set /p NUL=Processing file "C:\export\%%A"... <NUL
::Search the current file for the specified keyword, and store the line number in a variable
for /f "tokens=1,2 delims=:" %%B in ('findstr /inc:"%Keyword%" "%FilePath%\%%A" ^| findstr /n .*') do (
if "%%B" equ "1" set LineNumber=%%C
)>NUL
::Output all data from the current file to a temporary file, until the line number found above has been reached
for /f "tokens=1* delims=:" %%D in ('findstr /n .* "%FilePath%\%%A"') do (
if %%D lss %LineNumber% echo.%%E>>"%FilePath%\queue.tmp"
)>NUL
::Replace the current file with the processed data from the temp file
move /y "%FilePath%\queue.tmp" "%FilePath%\%%A">NUL
echo Done.
)
