Linux: exclude specific file types when running “locate”

Question

I'd like to configure locate to always exclude specific file types.

For example, I would like to exclude ".pyc" ".class" "~" etc.

Answer 1

This is a duplicate question from superuser.com:

In updatedb.conf, uncomment the PRUNENAMES line and add the extension .pyc. On my Ubuntu system by default it reads:

# PRUNENAMES=".git .bzr .hg .svn"

Change it to

PRUNENAMES=".git .bzr .hg .svn .pyc"

Answer 2

look at /etc/updatedb.conf

Answer 3

Hideous hack though it may be, you could always use grep:

locate foo | grep -v ".pyc$" | grep -v ".class$"

and chain as necessary.
