[expert] What the heck is this daily cron task?

[Chris Aakre]

What is this task:

[chris@localhost cron.daily]$ less slocate.cron  

#!/bin/sh
 
/usr/bin/slocate -u -f "udf,nfs,smbfs,ncpfs,proc,devpts,iso9660,usbdevfs" -e 
"/tmp,/var/tmp,/usr/tmp,/afs,/net"  

This annoying task looks around on my hard drive for half an hour, consuming 
50% of my CPU time on a PII 300. Is this needed? Can I cancel it? I have no 
idea what it's trying to do.

Thanks in advance.
