... chomp $dirname - why?

To get rid of that pesky newline. (Yes, there is one.)

... define the scalar $dirname - why?

That he may print it (in the last line)?

... use a system call to rm, making it platform dependant. Why not use unlink?

Opening "ls *~|" already makes it platform dependent. Of course, that could be glob("*~"), so your question still stands ...

... empty the entire directory from which this is run - why not use rm * | del *.* | whatever?

I think you miss the point: the alternative would be rm *~, which is quite easy to get wrong. Or at least easy enough to make guys like me paranoid.

Me, I have a bash function for this sort of thing:

function cleanup { rm "$@" *~ .*~ #* }

If it ever gets complicated enough that I make a Perl script out of it, I'll probably make it platform independant. For now, it does the job.

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.
