UPDATEDB(1L) UNIX Programmer's Manual UPDATEDB(1L)NAME
updatedb - update a file name database
SYNOPSIS
updatedb [options]
DESCRIPTION
This manual page documents the GNU version of updatedb,
which updates file name databases used by GNU locate. The
file name databases contain lists of files that were in par-
ticular directory trees when the databases were last
updated. The file name of the default database is deter-
mined when locate and updatedb are configured and installed.
The frequency with which the databases are updated and the
directories for which they contain entries depend on how
often updatedb is run, and with which arguments.
In networked environments, it often makes sense to build a
database at the root of each filesystem, containing the
entries for that filesystem. updatedb is then run for each
filesystem on the fileserver where that filesystem is on a
local disk, to prevent thrashing the network. Users can
select which databases locate searches using an environment
variable or command line option; see locate(1L). Databases
can not be concatenated together.
The file name database format changed starting with GNU find
and locate version 4.0 to allow machines with diffent byte
orderings to share the databases. The new GNU locate can
read both the old and new database formats. However, old
versions of locate and find produce incorrect results if
given a new-format database.
OPTIONS
--localpaths='path1 path2...'
Non-network directories to put in the database.
Default is /.
--netpaths='path1 path2...'
Network (NFS, AFS, RFS, etc.) directories to put in the
database. Default is none.
--prunepaths='path1 path2...'
Directories to not put in the database, which would
otherwise be. Default is /tmp /usr/tmp /var/tmp /afs.
--output=dbfile
The database file to build. Default is system-
dependent, but typically /usr/local/var/locatedb.
--netuser=user
The user to search network directories as, using su(1).
