You can also check into Getopt::Std or Getopt::Long, both of these modules give you more control over the command line. here is an example usage:

use Getopt::Long; Configure( \%Config ); if( $Config{help} ){ Syntax(); exit();} ....Code Goes Here..... sub Configure { my( $Config ) = @_; my $Result = 0; Getopt::Long::Configure( "prefix_pattern=(-|\/)" ); $Result = GetOptions( $Config, qw( del|d=i length|l=i path|p=s first|f=s reports|r=i help|?|h ) ); if (! scalar $Config->{line}) { $Config->{line}=132;} if (! scalar $Config->{reports}) { $Config->{reports}=1;} if (! exists $Config->{path}) { Syntax(); exit; } if (! exists $Config->{first}) { Syntax(); exit; } if (exists $Config->{del}) { Delete(); } $stream = $Config->{line}; $rptpag = $Config->{reports}; $dir = $Config->{path}; $firstln = $Config->{first}; } sub Syntax { print <<EOT; ansi.pl ------- Used for Adding/Removing ANSI printer control characters. Syntax: ansi.pl [-l length] [-p path] [-f first] [-r reports] [-d del] -l..........Defines length of each line in the files. [default +=132] -p..........Specifies the directory path to process. [must be +defined] (Directory must end with a \\) -f..........Defines the first line of a report. [must be defin +ed] -r..........Set the number of reports per page. [default=1] -d..........Deletes defined number of characters from beginnin +g of each line. [optional] -h..........This help screen. *(looks for all *.dat in specified directory, saves original t +o *.bak) EOT }
