As a general rule, I agree with all of your advice but there are definately exceptions to the rule.

Why do you want to run external programs?

Well, I want to use GNU Grep because it's orders of magnitude faster than the Perl version.

I think you sort of just ignore the whole sysadmin use of Perl because it's fine to rely on bashisms when you are root and know that your shell is bash. If you intend to release your code to the world, then yes, portability is a huge issue but not so much when it's a one off script to glue the server together.

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.
