( #3333=superdoc: print w/replies, xml ) Need Help??
After reading all these *very* helpful advices, here's what i've got:

use strict; use warnings; while() { my @loads; my $i = my $cpuload = 0; open(INFIL,"< /proc/stat") || die("Unable To Open /proc/stat\n"); <INFIL> =~ /^cpu\s+(\d+)\s+(\d+)\s+(\d+).*/; @loads = ($1, $2, $3); sleep 1; seek INFIL, 0, 0; <INFIL> =~ /^cpu\s+(\d+)\s+(\d+)\s+(\d+).*/; foreach ($1, $2, $3) { $cpuload += $_ - $loads[$i++]; } close(INFIL); print "$cpuload\n"; }

Tie::File looks interesting, so that might not be the final version ;)

Thanks a lot folks!

An idea is not responsible for the people who believe in it...

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.
