All command line args go into the global array @ARGV.
shift defaults to @ARGV (when it is not in a suboutine)...
More info on that is in the Perl predefined variables node.
for one arg, you can shift it, like so: my $var = shift
or, for many args:
my ($var1,$var2,var3,$var4)=@ARGV;

Which is kinda neat.
Also, you could access them directly: print $ARGV[0]
Well, there might be even more ways, but you get the idea, right? :)

Here's some code to play with.

#!/usr/bin/perl if ($#ARGV == 2) { # $#ARGV is number of args in @ARGV minus one my $foo = shift; #First arg; my $bar = shift; #second arg; my $baz = shift; #Last arg; #print it; print "You say $foo $bar $baz?\n"; } else { #Warn, and exit; warn <<TEXT; I need three arguments! Usage: $0 arg1 arg2 arg3 TEXT }

I hope that helps. :-)

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
