Short and to the point. This is probably too simple to deserve the title of "Tutorial", but this is where this is where some Monks look.

I've noticed that occassionally people try to use the command line, but don't quite "get" how to use modules and the import list. It's fairly simple. Use the -M command line switch, followed by the module name. For example, the following are equivalent:

use LWP::Simple; getprint( "http://www.perlmonks.org/" ); # command line: perl -MLWP::Simple -e 'getprint( "http://www.perlmonks.org/" )'

Some modules either require an import list be specified or are easier to use with an import list. In this case, use the -M switch followed by an '=', with import items separated by commas.

use CGI qw/:standard *table/; print start_table( { border => 2 } ); # command line perl -MCGI=:standard,*table -e 'print start_table({-border=>2})'

There, that wasn't too painful, was it?

  • 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 or How to display code and escape characters are good places to start.
