Module-free version. In brief:
perl -le '$size += (-f $_ ? -s _ : 0) for (<*>); print $size'
Unnecessarily cryptic, sorry. (-f $filename) checks whether something is a plain file, as opposed to a socket, directory, link, or some other weird beast. The above is in a for loop, so $_ is each filename coming out of <*>. (-s $filename) gives the size. Except that we've already called stat() on the file, so we don't want to take the time to do it again, which is what the magic underscore filehandle is good for.

Finally, <*> does a pattern match on the current directory. You may prefer to say glob("*").

Readable version:

my $size = 0; for my $filename (glob("*")) { next unless -f $filename; $size += -s _; }

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