This seems much too complicated for my liking.

I really don't like the way it needs to create a temporary file, and that it writes it output out to a fixed file, rather than STDOUT, thus letting me redirect it, or play with it in some other way. I'd go for something more along the lines of:

use strict; my %space; while (<>) { next unless m#^/#; next if m#^/proc#; next unless m#^[^ ]* *([^ ]*) *[^ ]* *([^ ]*) *[^ ]*#; $space{$ARGV}{total} += $1; $space{$ARGV}{free} += $2; } foreach my $host (sort keys %space) { printf "%s: %dk free, out of %dk, (%.2f%%)\n", $host, $space{$host}{free}, $space{$host}{total}, $space{$host}{free} / $space{$host}{total} * 100; }
Then I'd call it as: perl ~/dfk hosts/* > report

Playing with the format of the output is then trivial.

If you really want to be able to view the intermediate 'space' file, then you could add a command line parameter for it (including the name of the output file?).

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.
