( #3333=superdoc: print w/replies, xml ) Need Help??
Hey Monks, I would like to write a subroutine to look for command-line arguments such as -help, -h, and --help. I wanna call my subrutine from a main program and the thing is: if I give the program any of the named command-line arguments, when you pass them into the subroutine it should return a true value. If this is the case, the program should print out a help message in a $USAGE variable and exit. My try is:
#!/usr/bin/perl -w $check = mycheck($#ARGV); if ($check != 1) { $usage = "Help arguments have been found"; print $usage, "\n"; } sub mycheck { my($#ARGV) = @_; $return = 0; #Variable RETURN set as false (set as 0) foreach $arg (0 .. $#ARGV) { if (($arg eq '-help') || ($arg eq '-h') || ($arg eq '--help')) + { $return = 1; #Variable return now is true exit; } else { print "No help arguments found\n"; } } return $return }
But it looks like not working and I cannot find the reason. Any ideas? when I run it it returns "syntax error at line 13, near "0;" THANKS!

      Should cpanminus be part of the standard Perl release?
