slocate
slocate [options] string
Securely search database(s) of filenames and print matches. Works like locate, but it also stores file permissions and ownership information so users cannot see files to which they don't have access. In some distributions, locate is actually a symbolic link to slocate.

/etc/updatedb.conf , when updating the database.
