Perhaps I've totally missed the point, but if you want to add line numbers to your program, you could include this snippet in every program you write.
sub lines_count { open IN, "< $0" || die "Can't open file (black magic?)\n"; while( <IN> ) { chomp; printf "%3d: %s\n", $., $_; } close IN; }
So, you could type:

perl -e lines_count > something_that_let_you_print. (Maybe) Useful on system where wc does not exist.

Update Sorry, I've said something wrong. From perlrun...

-e commandline
may be used to enter one line of script. If -e is given, Perl will not look for a script filename in the argument list. Multiple -e commands may be given to build up a multi-line script. Make sure to use semicolons where you would in a normal program.
So what you could write is:

perl -e 'while (<>) {chomp; printf "%3d: %s\n", $., $_; }' < some_script > something_that_let_you_print

Sorry :)

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 or How to display code and escape characters are good places to start.
