Removing everything after specific character in batch - variables

SETLOCAL ENABLEDELAYEDEXPANSION
set "s=DIR D:\MyFolder /S /Q ^|FIND /i "Owner" ^|findstr /m /i "\.mkv$""
for /f "Tokens=5,6*" %%a in ('%s%') do (
SET _endbit=%%aa:*STRING=%
CALL SET _result=%%aa:%_endbit%=%%
>>%tmp%\list.txt echo %_result% %%b %%c
)
wscript "C:\my.vbs"
I am listing my files that owned by Owner and has extension mkv from MyFolder. I want to remove everything after specific character/word. I wrote that code. But It seems to be not working.
First of all, is it possible to do that? If so what is wrong with my code?

You came up with the same solution I was going to post on your other question - but I think you're missing some things. The line ending STRING=% is missing another % at the end, and the line %%aa:%_endbit%=%%, I'm not sure it can work directly on the variable from the for loop, and you need to store it in another variable first, and you probably need some expansions using ! characters too.
Here's what I had that seems to work, just as a test in a folder with three files in it, removing the end of the filename using E0 as the cutoff string:
SETLOCAL ENABLEDELAYEDEXPANSION
#echo off
for %%f in (*.mkv) do (
set FULLNAME=%%f
set ENDTEXT=!FULLNAME:*E0=!
call set TRIMMEDNAME=%%FULLNAME:!ENDTEXT!=%%
echo !TRIMMEDNAME!
)

Using a Batch file can you remove part of a file name from files in a folder and all sub folders?

Hi I am new at using batch files and I am struggling to find a way of removing part of a file name for multiple files in a folder and all sub-folder.
the files are all named like r1_c02_200111_145423_am.csv and I need to remove the _am from the files.
I have tried the following
FOR /R "C:\Users\bob\Documents\data\" %%G IN (*_am.csv) DO REN "%%G" *.csv
but this does not change anything.
can anybody point me in the right direction please?
With the help of such a script, you can perform the required operation.
#ECHO off
FOR %%i IN (*_am.csv) DO CALL :do_rename %%i
GOTO :eof
:do_rename
SET "_file=%1"
REN "%_file%" "%_file:~0,-7%.csv"
:eof
Now more.
The search in the question was correct. To perform a rename while passing through the FOR ... DO, you can use both the SETLOCAL EnableDelayedExpansion or a procedure call. I think it's easier to use a procedure call. you don’t have to puzzle over understanding (and misunderstanding) how the SETLOCAL EnableDelayedExpansion works.
For each iteration of the loop, the Wick procedure is called with the first argument of the file name passed to it:
CALL :do_rename %%i
In the procedure itself, the argument is converted to a variable. You can already use substring operations on the variable itself. More information about substring operations can be found here.
:do_rename
SET "_file=%1"
REN "%_file%" "%_file:~0,-7%.csv"

batch file passing variable to a text file

ECHO off
FOR /r %%a IN (*) DO (
IF NOT "%pth%"==%%~da%%~pa (
ECHO "%pth%">>Liste.txt
)
SET pth=%%~da%%~pa
)
I want to pass a path just one time; not for every file subdirectories includes. How %pth% string variable can be passed to a text file? Why does this code not work?
Is this code wrong?
FOR /r %%a IN (*) DO (
SET pth=%%~da%%~pa
ECHO %pth%>>Liste.txt
)
The code below works. It passes the paths for each file. If there is files more than one in a subdirectory it passes same path as many as the number o files. I don't want it. I want passing the same path once.
FOR /r %%a IN (*) DO ECHO %%~da%%~pa>>Liste.txt
You haven't told use very clearly (with an example) what you want to do.
Fundamentally, within a block statement (a parenthesised series of statements), the entire block is parsed and then executed. Any %var% within the block will be replaced by that variable's value at the time the block is parsed - before the block is executed - the same thing applies to a FOR ... DO (block).
Hence, IF (something) else (somethingelse) will be executed using the values of %variables% at the time the IF is encountered.
Two common ways to overcome this are 1) to use setlocal enabledelayedexpansion and use !var! in place of %var% to access the changed value of var or 2) to call a subroutine to perform further processing using the changed values.
Hence
#ECHO off
setlocal enabledelayedexpansion
FOR /r %%a IN (*) DO (
IF NOT "!pth!"=="%%~dpa" (
ECHO "!pth!">>Liste.txt
)
SET "pth=%%~dpa"
)
should work (I haven't tried it)
OR
for /r /d %%a in (*) do >>liste.txt echo %%a
which is probably easier (produce a listing of all subdirectories)
Note that %%~da%%~pa is equivalent to %%~dpa
Edited to include required "
#Magoo: Thanks. You show me the right.
The code below is which I want; but "if conditional" does not work: ("!pth!"==%%~dpa) check is always return FALSE I think.
#ECHO off
setlocal enabledelayedexpansion
FOR /r %%a IN (*) DO (
IF NOT "!pth!"==%%~dpa (
ECHO %%~dpa>>Liste.txt
)
SET "pth=%%~dpa"
)
#Magoo: The question is how the code above works like your one line code below:
for /r /d %%a in (*) do >>liste.txt echo %%a
or like written by #MC ND:
dir /ad /s /b >> liste.txt
At last this works. Thanks everyone.
code:
#ECHO off
setlocal enabledelayedexpansion
FOR /r %%a IN (*) DO (
IF NOT "!pth!"=="%%~dpa" (
ECHO %%~dpa>>Liste.txt
)
SET "pth=%%~dpa"
)
dir /ad /s /b >> liste.txt
This should do the same your code trying to do: append all the subfolders into the target file.
The problem with the original code is how the parser handles variables. In batch files, when a line or a block of lines is reached, the parser removes all variable reads, replacing them with its value before executing the code. So, if inside a line/block a variable is changed, this changed value can not be retrieved inside the same line/block as the read operation was removed. The usual way to handle it is to enable delayed expansion. This allows to change where needed variable read syntax from %var% into !var!, indicating to the parser that the read operation must be delayed until the code is executed.
So, in your case, filtering the path of the files
setlocal enabledelayedexpansion
set "pth="
FOR /r %%a IN (*) DO (
IF NOT "!pth!"=="%%~dpa" (
ECHO "%%~dpa">>Liste.txt
SET "pth=%%~dpa"
)
)
Put the IF %pth% condition outside the FOR and it should work.
What exactly do you want to do ? Perhaps theres a simpler way.

Set file name with * as variable batch script

I have a batch file that i'm having issues with. I need to find the name of a file, then set it to a variable. Then I will use this to pass it onto a vbs script to further look into the file. The name of the file is logfile_date_time.log but the time varies depending on what time is starts. The point of the batch file is to find out the last modified date of this file.
set fordate=%date:~4,2%%date:~7,2%%date:~10,4%
set filename=c:\logfile_%fordate%_*.log
if exist %filename% (goto exist) else (goto noexist)
:exist
vbsscript.vbs /file:%filename%
goto end
:noexist
file doesn't exist code blah blah
:end
pause
I had to modify the names of folders and remove some code for security purposes since this is for work.
Any help appreciated. Thanks!
not tested:
set "last_modified="
for /f "delims=" %%f in ('dir /a-d /tw /o-d /b^| findstr /r /i /c:"logfile_[0-9][0-9]*_.log"') do (
do set "last_modified=%%~dpfnxf"
goto :break_loop
)
:break_loop
if defined last_modified echo file %last_modified% exist ...
The problem with your code is that it doesn't expand the wildcard character (*), and your VBScript probably doesn't handle wildcards in filenames by itself (the FileSystemObject methods for instance don't). If the file you want to process is the only one matching your pattern, you could do something like this:
#echo off
setlocal
set "fordate=%date:~4,2%%date:~7,2%%date:~10,4%"
pushd C:\
for %%f in (logfile_%fordate%_*.log) do vbsscript.vbs /file:"%%~ff"
popd

How can i remove the extension of a filename which is saved in a batch variable?

first my batch script snippet (not working):
set _WRx32=wrar420.exe
set _WRx64=winrar-x64-420.exe
set _WRLNG=rarlng.rar
FOR %%f IN (_WRLNG, _WRx64, _WRx32) do set "%%f"="%%~nf"
[ for every variable name (!) in the list remove the extension from the variable content (!)
and save back to the same variable ]
Question: How can i remove the extension of the filenames which are saved in the
variables _WRLNG, _WRx64, _WRx32 and save this filename (without extension)
back to the same variables ??
i need something like: set var=%var~n% but that doesn't work. And in a FOR loop i don't know
how to convert the name from the (...variable names ...) list to the corresponding variable
so i can apply a parameter extension like "~n", "~nf" etc. on it.
Can anyone help me ?
Thanks
#echo off
setlocal EnableDelayedExpansion
set _WRx32=wrar420.exe
set _WRx64=winrar-x64-420.exe
set _WRLNG=rarlng.rar
FOR %%f IN (_WRLNG, _WRx64, _WRx32) do (
FOR %%g in (!%%f!) do set "%%f=%%~ng"
)
Try this:
FOR /f "delims=." %%f IN ("%_WRx32%") do set "_WRx32=%%f"
FOR /f "delims=." %%f IN ("%_WRx64%") do set "_WRx64=%%f"
FOR /f "delims=." %%f IN ("%_WRLNG%") do set "_WRLNG=%%f"
I tried a similar version on the command line, and it appears you can't do multiple variable variables in a for loop (that I know of).
So, you have two options:
If you know that the variables will always have a 4 character extension (including the period), then you could use something like set _WRLNG=%_WRLNG:~0,-4%. This will take the last 4 characters from the variable.
You have to do one loop per variable, and you need to fix up the way you are doing them. The proper way would be for /f %%i in ("%_WRLNG%") do set _WRLNG=%~ni.
Or, look at Endoro's answer for a better for loop example.
EDIT: Thought of another way:
#echo off
for /f "delims=. tokens=1,2" %%i in ("%var%") do set var=%%i

DOS Batch file - Copy file based on filename elements

I need to sort alot of files based on their filename. I would like to use a batch file to do it. I do know what I want but I am not sure of the correct syntax.
Example of filenames I work with: (They are all in the same directory originally)
2012_W34_Sales_Store001.pdf
2012_W34_Sales_Store002.pdf
2012_W34_Sales_Store003.pdf
2012_November_Sales_Store001.pdf
2012_November_Sales_Store002.pdf
2012_November_Sales_Store003.pdf
I would like to extract the information that are located between the "_" signs and put them into a different variable each time. The lenght of the informations contained between the _ signs will be different everytime.
Example:
var1="2012"
var2="W34" (or November)
var3="Sales"
var4="001"
If I am able to do this, I could then copy the files to the appropriate directory using
move %var1%_%var2%_%var3%_%var4%.pdf z:\%var3%\%var4%\%var1%\%var2%
It would need to loop because I have Store001 to Store050.
Also, there are not only Sales report, many others are available.
I hope I am clear.
Please help me realize this batchfile!
This script will make sure that it only attempts to move files that meet the pattern part1_part2_part3_part4.pdf
#echo off
for /f "eol=_ delims=" %%F in (
'dir /b *^|findstr /ix "[^_]*_[^_]*_[^_]*_[^_]*[.]pdf'
) do for /f "eol=_ tokens=1-4 delims=_." %%A in ("%%F") do (
move "%%F" "z:\%%C\%%D\%%A\%%B"
)
If needed, you could add md "z:\%%C\%%D\%%A\%%B" 2>nul before the MOVE in case the folders might not exist yet.
This script will move your files based on the values between the underscore to a like wise constructed path.
for %%f in (*.pdf) do call :handlefile %%f
:handlefile
set pad=z:
for /f "delims= tokens=1,* " %%a in ("%1") do call :step %%a %%b
rem this MOVES the file, maybe use echo first for testing
move "%fn%" "%pad%"
exit /B
:step
if !%2!==!! EXIT /B
set pad=%pad%\%1
for /f "delims=_ tokens=1,* " %%a in ("%2") do call :step %%a %%b
EXIT /B
