- @REM - CheckParameters.BAT (23 Jun 2024 // 30 Jun 2024 / 23 Jun 2024): How to Check Parameters -- Native vs 3rd Party
- @ECHO OFF
- ::: If you want to check for a parameter of /X or -X, the use the following format:
- ::: CALL :GetParams "X EXTENDED" & IF DEFINED #OK (execute whatever commands you want here)
- :::
- ::: You would call this from the command-line as:
- ::: CheckParameters.BAT /X
- ::: CheckParameters.BAT -X
- ::: -----------------------------------------------
- :::
- ::: If you want to check for a parameter of /X or -X that contains a value, then use the following format:
- ::: CALL :GetParams "X EXTENDED" #X_VARIABLE & IF DEFINED #X_VARIABLE (execute whatever commands you want here)
- :::
- ::: You would call this from the command-line as:
- ::: CheckParameters.BAT /X:1
- ::: CheckParameters.BAT /X:NoSpaces
- ::: CheckParameters.BAT /X:"Value with Spaces"
- :::
- ::: You can do this natively or with a 3rd party utility that really streamlines the process.
- ::: I use this for pretty much all of my major scripts.
- :::
- ::: The :FoundParam routine is just here for testing. Not needed for production at all.
- ::: All you need for this to work is the variable block, and EITHER :GetParams OR :GetParams2
- :::
- ::: Full script can be found here ..... https://pastebin.com/wjs4Hz5k
