so believe i'm having issues syntax in batch file trying write. i'm new writing batch files, , still learning how language works. essentially, have script can run -run , additional commands:
scriptname -run -prereq i want able have menu commands can run script:
scriptname -help followed more input parameters user wants for
** enter additional input commands script help: user input like:
-prereq -one -two -three the -run command should run , apply commands.
the -help command should echo information requested commands.
just running script no -run or -help command prints basic header version, time, , explanation -help exists (as seen in code below)
basically, -run should call processes depending on applied, can seen label :process_args similarly, -help first take -help command initiate, , ask more parameters, seen in :help_process_args call labels echo information.
the functionality seems work, if run script no -run parameter, defaults -run functionality. also, keep seeing syntax errors try fix default behavior.
can see why -help works, , why code defaults -run behavior no parameters, instead of printing short header? also, there syntax errors obvious? (again, i'm new batch files)
here's relevant code shows menu creation , calls run , processes.
