Determining if batch script has been started/executed from the command line (cmd) -or- To pause or not to pause?

Question

I like to have a typical \"usage:\" line in my cmd.exe scripts — if a parameter is missing, user is given simple reminder of how the script is to be used.

Answer 1

This is only using the internal command. so effectively....

EnableDelayedExpansion

if "!cmdcmdline!" neq "!cmdcmdline:%~f0=!" pause >nul

or

if not "!cmdcmdline!" == "!cmdcmdline:%~f0=!" pause >nul

DisableDelayedExpansion

if "%cmdcmdline%" neq "%cmdcmdline:%~f0=%" pause >nul

or

if not "%cmdcmdline%" == "%cmdcmdline:%~f0=%" pause >nul
