Hello All,
I'm trying to create a script with where you can put a flag to the script or not fx run it like:
script -h or just script
something like:
if ( $ARGV[0] =~ /-h/ ) {
Try if(defined $ARGV[0]) { if($ARGV[0] eq '-h') { print "Welcome to dash h\n"; } else { print "What did you choose?\n"; } } else { print "you have not chosen the very special ability!\n"; }
or:
my $switch = $ARGV[0] || ''; now it is initialized :) and you can do what you did before just use $switch instead of $ARGV[0]
HTH
Lee.M - JupiterHost.Net
print "You have chosen the very special ability!\n"; } else { print "you have not chosen the very special ability!\n"; }
but when I run this one without any flag i get an error message: "use of initialized value in pattern match (m//)"
Do I have to do it differently to get rid of the error?
Thanks, Jakob
