I'll address one point. Grandfather gave good advice.

3. -e vs -f. The documentation is not super clear about this. Basically a directory is also a "file", albeit a special one. The -e test will return true if the name is a directory or some other weirdo things that aren't relevant now. The -f test will return true if (a)the file exists AND (b)the file is a "plain file". Use the -f test. The -e test can return true for some things that aren't simple readable files.

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.


There's more than one way to do things
