Should this move to Obfuscated Code? :-)

perl -F: -al0ne '$i||=1;/^n/&&print$i;!/^u/&&print$F[1];/^$/&&$i++&&pr +int$/'

I don't think it meets the "simple" requirement, but it is mostly on one line... ;-)

Here is what B::Deparse makes of it though, for reference.

LINE: while (defined($_ = <ARGV>)) { chomp $_; @F = split(/:/, $_, 0); $i ||= 1; print $i if /^n/; print $F[1] if not /^u/; print $/ if /^$/ and $i++; }

I'm not sure if the preceeding number is a requirement or not. Without the number prefix, I can get down to:

perl '-F: ' -al0ne '!/^u/&&print qq($F[1] );/^$/&&print$/'

(To run on Win32, change all the ' into " - it should still work.)

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.
