A pipe passes the output of one command to the input of another. So, to read the output of your echo command, read from STDIN. An example myscript.pl might be:

#!/usr/bin/perl
print <>;

Alternatively, if you really do just want to read standard input, you can read the predefined filehandle STDIN. For instance, to add line numbers to all lines coming from your pipe, you could do this:

#!/usr/local/bin/perl -w
use strict;
while (<STDIN>) {
  print "$. $_"
}
[download]

But almost any program is more useful if it can read either STDIN or filenames supplied on the command line. So reading <> almost always makes more sense.

Oft-used command line switches related to this subject are -p, -n, and -a (especially in conjunction with -F). See perlrun for how they work and what they do.

hdp.

Okeeee, that was ALLOT simpler then I thought but it works exactly like I want, thanks allot.
