NAME
udpatedb - update a database for mlocateSYNOPSIS
updatedb [OPTION]...
DESCRIPTION
updatedb creates or updates a database used by locate(1). If the database already exists, its data is reused to avoid rereading directories that have not changed.updatedb is usually run daily by cron(8) to update the default database.
EXIT STATUS
updatedb returns with exit status 0 on success, 1 on error.OPTIONS
The PRUNE_BIND_MOUNTS, PRUNEFS and PRUNEPATHS variables, which are modified by some of the options, are documented in detail in updatedb.conf(5).- -f, --add-prunefs FS
- Add entries in white-space-separated list FS to PRUNEFS.
- -e, --add-prunepaths PATHS
- Add entries in white-space-separated list PATHS to PRUNEPATHS.
- -U, --database-root PATH
- Store only results of scanning the file system subtree rooted at PATH to the generated database. The whole file system is scanned by default.
locate(1) outputs entries as absolute path names which don't contain symblic links, regardless of the form of PATH.
- -h, --help
- Write a summary of the available options to standard output and exit sucessfully.
- -o, --output FILE
- Write the database to FILE instead of using the default database.
- --prune-bind-mounts FLAG
- Set PRUNE_BIND_MOUNTS to FLAG, overriding the config file.
- --prunefs FS
- Set PRUNEFS to FS, overriding the config file.
- --prunepaths PATHS
- Set PRUNEPATHS to PATHS, overriding the config file.
- -l, --require-visibility FLAG
- Set the ``require file visibility before reporting it'' flag in the generated database to FLAG.
If FLAG is 0 or no, locate(1) outputs the database entries even if the user running locate(1) could not have read the directory necessary to find out the file described by the database entry.
If FLAG is 1 or yes (the default), locate(1) checks the permissions of parent directories of each entry before reporting it to the invoking user. To make the file existence truly hidden from other users, the database group is set to slocate and the database permissions prohibit reading the database by users using other means than locate(1), which is sgid slocate.
- -v, --verbose
- Output path names of files to standard output, as soon as they are found.
- -V, --version
- Write information about the version and licence of locate on standard output and exit sucessfully.
FILES
- /etc/updatedb.conf
- A configuration file. See updatedb.conf(5).
- /var/lib/mlocate/mlocate.db
- The database updated by default.
SECURITY
Databases built with --require-visibility no allow users to find names of files and directories of other users, which they would not otherwise be able to do.NOTES
The accompanying locate(1) utility was designed to be compatible to slocate and attempts to be compatible to GNU locate where possible. This is not the case for updatedb.AUTHOR
