CMD Directory Listing Substring Variable Length

Question

setlocal

wscript "C:\my.vbs" 

Hey guys, I have this code. Getting mkv files owned by Owner from MyFolder. And shows them via VBS.

And these are my files.

The.Leftovers.S01E02.720p.BLABLABLA
Falling.Skies.S04E03.720p.BLABLABLA

I want to limit the length to 20 letters. Or remove before the 720p

The.Leftovers.S01E02
Falling.Skies.S04E03

I read some guides but I couldn't import them into for /f "Tokens. Is it possible to do that? If so how?

Answer 1

Here is a batch file which will list the contents of the current directory, trimming all the names to 20 characters.

SETLOCAL ENABLEDELAYEDEXPANSION
@echo off

for %%f in (*) do (
    set TMPF=%%f
    echo !TMPF:~0,20!

)

For more help, run SET /? for help about the ~0,20 syntax and examples, and CMD /? for what the ENABLEDELAYEDEXPANSION does and what the !! does.

I can't for sure say how this would fit in your code, but maybe something like:

SETLOCAL ENABLEDELAYEDEXPANSION
for /f "Tokens=5,6*" %%a in ('%s%') do (
    set TMPA=%%a
    >>%tmp%\list.txt echo !TMPA:~0,20! %%b %%c
)
