Perl: Simple way to read Command line arguments
Parsing command-line arguments in Perl is very easy.
All the command-line arguments are present in the array $ARGV. You can get the number of arguments passed as ( $#ARGV + 1 ).
Below is a sample Perl script to read the command-line parameters.
#!/usr/bin/perl #-------------------------------------------------# # File: argv.pl # # Author: Dipin Krishna [email protected] # #-------------------------------------------------# # The commandline arguements are present in the variable $ARGV. $numberofArgs = $#ARGV + 1; print "The $numberofArgs command-line arguments are:\n"; foreach $argnum (0 .. $#ARGV) { print " $argnum.\t$ARGV[$argnum]\n"; }
