UPDATEDB(1L)UPDATEDB(1L)NAMEupdatedb - update a file name database
SYNOPSISupdatedb [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
particular 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 argu-
ments.
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 envi-
ronment 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). Default is daemon.
--old-format
Create the database in the old format instead of
the new one.
--version
Print the version number of updatedb and exit.
--help Print a summary of the options to updatedb and
exit.
