c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le "my $s = 'first|second|third'; my @ra = split '[|]', $s; dd \@ra; " ["first", "second", "third"]
Also works with  "[|]" and  /[|]/

Update: The reason  "\|" doesn't work is that in double-quote interpolation, the  \ (backslash) acts, in this case, on the  | (pipe) to produce a literal pipe. Double-quotish interpolation would need a doubled backslash to yield a single literal backslash in the compiled string:

c:\@Work\Perl\monks>perl -wMstrict -MData::Dump -le "my $s = qq{\|}; print qq{:$s:}; ;; my $t = qq{\\|}; print qq{:$t:}; " :|: :\|:
That's why it's generally better to use  qr{pattern} to compile a regex. (I use  qq{...} in the example because Windows command line uses "..." to quote everything and  qq{...} reduces the need for backslashes.) Contrast with  '\|' and  '\\|' Please see Quote and Quote-like Operators and Quote-Like Operators.

Title:
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.
