MS-DOS only: Enable variable expansion from inside of FOR loops with !varname!

setlocal enabledelayedexpansion
Usually the MS-DOS cmd.exe processes in the whole FOR loop as one command and expands each var like %varname% in before (except the loop var of course). This command enables expansion of other vars than only the loop var during the FOR loop. The syntax of the var to expand is then !varname! inside the FOR loop. Use command endlocal to end the setlocal command. E.g. (only works from batch files, not from commandline directly): @echo off setlocal enabledelayedexpansion FOR %%A IN (*) DO ( set file=%%A echo !file! ) endlocal

Hi ozymandias. That's not a bash command. As the tags shows, this is a MS-DOS batch command.
