To amplify mkmcconn's neat RTM answer, Getopt::Long does do exactly what you need.

I'm used to the very C-ish Getopt::Std, which is pretty much a reimplementation of the C function, so expected the same out of Getopt::Long, only word-oriented and using the BSDish -- flag indicator. Wrongo.

Getopt::Long has all sorts of DWIMmery to accept flags with one or two dashes, increment, and anything else. So, you can just use:

GetOptions('v+', \$verbose);

and you will get the behavior you desire from

scriptname -v -v -v

Thanks, mkmcconn!

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.
