Question

Suppose I wanted to echo every executable inside the %programfiles% folder

cd %programfiles%
for /r . %i in (*.exe) do echo "%~i"

but it yields

c:\program files\program1\program1.exe
c:\program files\program2\program2.exe

and I want

program1\program1.exe
program2\program2.exe

How to remove those prefixes?

Answer 1

You could use the string replace function of batch

pushd %programfiles%
set "prefix=%programfiles%"
setlocal DisableDelayedExpansion
for /r . %i in (*.exe) do (
  set "progPath=%~i"
  setlocal EnableDelayedExpansion
  set "progPath=!progPath:%prefix%=!"
  echo !progPath!
  endlocal
)
popd
