How Do I Read Command-line Arguments With Perl

How Do I Read Command-line Arguments With Perl


  • 29 Dec, 2011

    With Perl, command-line arguments are stored in the array named @ARGV.$ARGV[0] contains the first argument, $ARGV[1] contains the second argument, etc.$#ARGV is the subscript of the last element of the @ARGV array, so the number of arguments on the command line is $#ARGV + 1.Here's a simple program:#!/usr/bin/perl$numArgs = $#ARGV + 1;print "thanks, you gave me $numArgs command-line arguments.n";foreach $argnum (0 .. $#ARGV) {print "$ARGV[$argnum]n";}
