extracting file name from an environment variiable

I know that you can parse complete file path names easily when expanding batch file parameters.

For example, you may execute the following command line:

PROCESS.BAT C:WINDOWS\NOTEPAD.EXE

where process.bat contains the following line:

@ECHO %~NX1

The results would be:

NOTEPAD.EXE

But is there a way to easily parse environment variables in a siimilar way? or a way to convert the environment variable into a parameter so I may use these file name parsing functions on it?

show an example of that env var you want to parse and what you expect your final output to look like.

Hi ghost,

ok, lets say I have the variable: %XXX% which contains:

c:\program files\some folder\program.exe

I would like the to extract just the file name from that:

program.exe

Code: Select all

@echo off
set "testvar=c:\tmp\test.txt"
call :process %testvar%
goto :eof

:process
echo %~nx1
goto :eof
