in reply to Can't print data from the input file in Command Line processing.

Also note that you could make your main loop much simpler using the <> operator.

#!/usr/bin/perl -w use strict; use Getopt::Std; my $prog = $0; $prog =~ s|.*/||; my %opts; getopts('o:', \%opts); my $cmd = $opts{o} || 1; my %wordDb = (); # Works exactly like your posted code is supposed to while(<>) { print "$ARGV ==> $_"; }
