A small script that rewrites the command it gets as argument, passing any further arguments on, to send stdout and stderr to a log file that is rotated on each run.

Remember to edit the logdir variable to your settings (keep a trailing / or the last part will be prepended to the logfile). The keep variable controls how many old logs should be kept. The command name is prepended to each logfile.

I.e.: logit.py xcompmgr -Cc -r2 -t-3 -l-3 -fF -D5 &

#! /usr/bin/python
print """logit.py - Executes a program redirecting stdout and stderr to a rotating logfile by
adding the '>' character to the command and executing it through os.system ().

This software is not guaranteed to work or not do any harm to your system, use with caution.
