Here is a link to a thread where we came up with a perl solution for automagic log rotating based upon number of entries. This by-passes syslogd so it might or might not be useful to you.

http://www.freebsdforums.org/forums/...3949#post13949

The perl code is as follows:

Code:
#!/usr/bin/perl

# Real cheezy attempt at piping STDOUT into a perl routine to automagically
# rotate logs. Idea inspired by cRock.
# Auswipe sez "Hey, no guarantees!"

my $lineCounter = 0;
my $logCount    = 1;

#open(LOGFILE, ">app.log.$logCount");

while (true) {
  if (($lineCounter > 1000) || ($lineCounter == 0)) {
    close(LOGFILE);
    open(LOGFILE, ">app.log.$logCount");
    $logCount++;
    $lineCounter = 1;
    # print STDERR "Rolled log to app.log.$logCount\n";
  };
  $logEntry = <STDIN>;
  $lineCounter++;
  print LOGFILE "$logEntry";
  #print STDERR "Made log entry.\n";
};

Sample usage:

Code:
./someapp | ./perl_buffer

NAME
mkmanifest - create a shell script to restore Unix filenames SYNOPSIS
mkmanifest [ files ] DESCRIPTION
Mkmanifest creates a shell script that will aid in the restoration of Unix filenames that got clobbered by the MSDOS filename restrictions. MSDOS filenames are restricted to 8 character names, 3 character extensions, upper case only, no device names, and no illegal characters. The mkmanifest program is compatible with the methods used in pcomm, arc, and mtools to change perfectly good Unix filenames to fit the MSDOS restrictions. EXAMPLE
I want to copy the following Unix files to a MSDOS diskette (using the mcopy command). very_long_name 2.many.dots illegal: good.c prn.dev Capital Mcopy will convert the names to: very_lon 2xmany.dot illegalx good.c xprn.dev capital The command: mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital > manifest would produce the following: mv very_lon very_long_name mv 2xmany.dot 2.many.dots mv illegalx illegal: mv xprn.dev prn.dev mv capital Capital Notice that "good.c" did not require any conversion, so it did not appear in the output. Suppose I've copied these files from the diskette to another Unix system, and I now want the files back to their original names. If the file "manifest" (the output captured above) was sent along with those files, it could be used to convert the filenames. SEE ALSO
