Re: Locate Vs Find

[lindax newbie <linux-newbie@tlinx.org>]

If you look at the 'updatedb' script, you'll even find that it uses
the 'find' command to build the static database.  Normally the database
is rebuilt only once per/day -- in the wee hours of the morning if
your computer is on then otherwise, it'll run soon after you turn it
on in the morning (in the default configuration).  As Jagadeesh says,
locate is much faster -- basically being a "grep" through a large text
database, but it doesn't contain all the same info as 'find' can access
and is only up-to-date from when it was last run...
