8 documents the GNU version of
10 which updates file name databases used by GNU
12 The file name databases contain lists of files that were in
13 particular directory trees when the databases were last updated.
14 The file name of the default database is determined when \fBlocate\fP
15 and \fBupdatedb\fP are configured and installed. The frequency with
16 which the databases are updated and the directories for which they
17 contain entries depend on how often \fBupdatedb\fP is run, and with
20 In networked environments, it often makes sense to build a database at
21 the root of each filesystem, containing the entries for that filesystem.
23 is then run for each filesystem on the fileserver where that
24 filesystem is on a local disk, to prevent thrashing the network.
25 Users can select which databases \fBlocate\fP searches using an
26 environment variable or command line option; see \fBlocate\fP(1L).
27 Databases can not be concatenated together.
29 The file name database format changed starting with GNU
33 version 4.0 to allow machines with diffent byte orderings to share
34 the databases. The new GNU
36 can read both the old and new database formats.
37 However, old versions of
41 produce incorrect results if given a new-format database.
44 .B \-\-localpaths='\fIpath1 path2...\fP'
45 Non-network directories to put in the database.
48 .B \-\-netpaths='\fIpath1 path2...\fP'
49 Network (NFS, AFS, RFS, etc.) directories to put in the database.
52 .B \-\-prunepaths='\fIpath1 path2...\fP'
53 Directories to not put in the database, which would otherwise be.
54 Default is /tmp /usr/tmp /var/tmp /afs.
56 .B \-\-output=\fIdbfile\fP
57 The database file to build.
58 Default is system-dependent. In Debian GNU/Linux, the default
59 is /var/lib/locate/locatedb.
61 .B \-\-netuser=\fIuser\fP
62 The user to search network directories as, using \fBsu\fP(1).
63 Default is \fBdaemon\fP.
