( #3333=superdoc: print w/replies, xml ) Need Help??
I tested this on my WinXP 32 bit machine. It works fine. Something is wrong with your command line, what I don't know. But there is no fundamental need to escape the " characters. A side effect of a Windoze command line could be true.
#!/usr/bin/perl use warnings; use strict; my %accounts = ( tom => "BigApple", tom2 => "BigApple2", tom3 => "BigApple3", tom4 => "BigApple4", tom5 => "BigApple5", tom6 => "BigApple6", tom7 => "BigApple7", ); # sort the users in descending order my $counter = 1; for my $userID (reverse sort keys %accounts) { print "$userID\t"; print "\n" if $counter++ % 3 == 0; } __END__ Prints: tom7 tom6 tom5 tom4 tom3 tom2 tom

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.
