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

Please use findstr

echo %cmdcmdline% | findstr /ic:"%~f0" >nul && ( pause >nul )

or

setlocal EnableDelayedExpansion
.
.
echo !cmdcmdline! | findstr /ic:"%~f0" >nul && ( pause >nul )
.
.
endlocal

This is always worked...
