How Can I Auto Delete my Binary Files?

[Shaun Adams]

I'm running a RHEL 4.1 and MySQL 4.0.26.... 

so a lot or the more recent commands available in 5.0.x aren't available to
me. Does anyone know of any scripts or anything I can use to delete files
that arent being used or run by my slave servers? It's pretty safe to say
that I can delete log files older than 7 days so that can eliminate the need
to check for open files.
