Getting the quotes right can be quite daunting, that's why there's help via Sysadm::Install from CPAN: Let's whip up a script one_liner really quickly:

#!/usr/bin/perl # one_liner - produce a perl one-liner out of perl code use Sysadm::Install qw(:all); my $in = join "", <>; $in =~ s/\n/ /g; print "perl -e ", qquote($in, ':shell'), "\n";

Now, if you call one_liner without arguments, it'll wait for code to be typed into STDIN, terminated by CTRL-D, and spit out the one-liner right after:

$ one_liner print "hello\n"; print "world\n"; ^D perl -e "print \"hello\\n\"; print \"world\\n\"; "

Produces properly escaped one-liners out of any messy perl code you paste in.

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.
