walamab has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to take parameters from the command line at execution. Is this possible with perl? If so, how is it done? Thanks!

    No such thing as $ARGC, as far as I know.

    But yes, you can use @ARGV to get the command line args. Something to be aware of is that 

    $ARGV[0]

    is not the command name; it's the first argument.

    Also, check out the Getopt family of modules for automatically parsing your command line args: 

    perldoc Getopt::Std
perldoc Getopt::Long

    and more.

    $#argv is the same as argc. And as mentioned by another poster, $argv[0] is not the command name, rather $0 is.

    try the @ARGV array. $ARGV[0] is the first commandline parameter, though.

      my $argc = @ARGV;

print "There are $argc args.\n";

        Nice, you answered a ten-year old, already perfectly answered question with an unnecessary two-liner... ;-)

    while(<>) { } This will allow you to read input from the command line, its all in the camel book, a must have for all level of perl programmer.
