From all the reading I've done, and from all the advice I've been given, I make it a practice to *always* use warnings and strict, like this:

#!/usr/bin/perl -w
use strict;
[download]

Doing that will save you some pain in that it won't allow you to do things like use variables before you declare them.

Check out the perl style guide where "warnings" and "strict" are described, by doing

   perldoc perlstyle
[download]

at a command prompt.

HTH.

• 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.
