Ive been handling webserver with more than 1000 website and lots of unique visitors per month. Session are stored on the server hard drive and every end of the month i need to clean it up.

Now i was puzzled by rm command.
rm -f *

in /tmp/ directory. The terminal choked and gave out:

-bash: /bin/rm: Argument list too long

Apparently there are a maximum number of files that can be passed to rm.

ls -1 | grep sess | wc -l

382611

wow 382611 session files! image how long it would take if you have an application that running with sessions.
The solution for this problem would be :

find . -name 'sess*' | xargs rm
