Answer: 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. Example Perl command line arguments program Here's a simple Perl program that prints the number of command-line arguments it's given, and the values of the arguments: #!/usr/bin/perl #---------------------# # PROGRAM: argv.pl # #---------------------# $numArgs = $#ARGV + 1; print "thanks, you gave me $numArgs command-line arguments.\n"; foreach $argnum (0 .. $#ARGV) { print "$ARGV[$argnum]\n"; }
