How to stop updatedb from indexing backup drive?

[minckster]

Whew! Here's the line to add to .bashrc to redefine 'locate' so it excludes everything on the backup drive:

# Exclude the backup drive from locate's results
function locate() { command locate $1 | grep -vw \/Volumes\/Backup\ HD; echo "  ***REM: I redefined locate to exclude Backup HD***"; }

Of course the 'echo' part isn't required. I want it there in case something goes wrong with my custom 'locate,' so I won't forget that I had customized it.

I'm not quite sure if it should be '$1', '$*' or '$@'. '$1' seemed safest.
