PS, perldoc is your friend...


laptop:~> perldoc -f chop

chop VARIABLE
chop LIST
chop    Chops off the last character of a string and
        returns the character chopped.  It is much more
        efficient than "s/.$//s" because it neither scans
        nor copies the string.  If VARIABLE is omitted,
        chops $_.  If VARIABLE is a hash, it chops the
        hash's values, but not its keys.

        You can actually chop anything that's an lvalue,
        including an assignment.

        If you chop a list, each element is chopped.  Only
        the value of the last "chop" is returned.

        Note that "chop" returns the last character.  To
        return all but the last character, use "sub-
        str($string, 0, -1)".

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.
