updatedb - update a file name database
Синопсис (Synopsis)
updatedb [options]
Описание (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 determined 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(1). Databases cannot be concatenated
together.
The LOCATGE02 database format was introduced in GNU findutils
version 4.0 in order to allow machines with different byte
orderings to share the databases. GNU locate can read both the
old and LOCATE02 database formats, though support for the old
pre-4.0 database format will be removed shortly.
Параметры (Options)
--findoptions='-option1 -option2...'
Global options to pass on to find. The environment
variable FINDOPTIONS also sets this value. Default is
none.
--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. The environment variable NETPATHS also sets
this value. Default is none.
--prunepaths='path1 path2...'
Directories to not put in the database, which would
otherwise be. Remove any trailing slashes from the path
names, otherwise updatedb won't recognise the paths you
want to omit (because it uses them as regular expression
patterns). The environment variable PRUNEPATHS also sets
this value. Default is /tmp /usr/tmp /var/tmp /afs.
--prunefs='path...'
File systems to not put in the database, which would
otherwise be. Note that files are pruned when a file
system is reached; any file system mounted under an
undesired file system will be ignored. The environment
variable PRUNEFS also sets this value. Default is nfs NFS
proc.
--output=dbfile
The database file to build. Default is system-dependent.
In Debian GNU/Linux, the default is
/var/cache/locate/locatedb.
--localuser=user
The user to search non-network directories as, using
su(1). Default is to search the non-network directories
as the current user. You can also use the environment
variable LOCALUSER to set this user.
--netuser=user
The user to search network directories as, using su(1).
Default is daemon. You can also use the environment
variable NETUSER to set this user.
--dbformat=F
Create the database in format F. The default format is
called LOCATE02. Alternatively the slocate format is also
supported. When the slocate format is in use, the
database produced is marked as having security level 1.
If you want to build a system-wide slocate database, you
may want to run updatedb as root.
--version
Print the version number of updatedb and exit.
--help Print a summary of the options to updatedb and exit.
Ошибки (баги) (Bugs)
The updatedb program correctly handles filenames containing
newlines, but only if the system's sort command has a working -z
option. If you suspect that locate may need to return filenames
containing newlines, consider using its --null option.
