I like this problem.

Personally, I would keep a hash of filehandles, but close one at random if there are too many open (hoping the pids are kinda grouped together in the logfile).

use strict; my %handles = (); sub open_one { my $pid = shift; return $handles{$pid} if exists $handles{$pid}; while( (my @k = keys %handles) > $threshold ) { my $toclose = $k[ int rand @k ]; close $handles{$toclose}; delete $handles{$toclose}; } open $handles{$pid}, ">>", "logfile-$pid.log" or die "hrm: $!"; return $handles{$pid}; } sub scanner { # ... boring things if( m/something/ ) { my $pid = $1; my $fh = &open_one($pid); print $fh $stuff; } # boring things... }

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.
