I am writing the script for "option" while getting arguments from command line, and below I have code,
use strict; use warnings; use Getopt::Std; my %options; if (scalar @ARGV < 3) {usage()}; sub usage { print STDERR << "EOF"; \nThis program does... usage: $0 [-hcfo] -h : this (help) message -c : config file -o : Fj xcf release file -x : output file EOF exit; } getopts ("hc:f:o:", \%options); usage() if $options{h}; my $source_file= $options{o}; my $dest_file= $options{x}; my $config_file= $options{c};
And in above code, I want to "-o" to be optional for example if user don't provide "-o(filename)" that means value for $source_file then I want to take default file suppose "source.txt"; Could any one guide me how can that be done?Please. Cheers
