       updatedb - update a database for plocate


       updatedb [OPTION]...


       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 from a systemd.timer(8) to update the default database.


       updatedb returns with exit status 0 on success, 1 on error.


       The PRUNE_BIND_MOUNTS, PRUNEFS, PRUNENAMES 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.

       -n, --add-prunenames NAMES
              Add entries in white-space-separated list NAMES to PRUNENAMES.

       -e, --add-prunepaths PATHS
              Add entries in white-space-separated list PATHS to PRUNEPATHS.

       -e, --add-single-prunepath PATH
              Add PATH to PRUNEPATHS. Note that this is currently the only way to add a path with
              a space in it.

       -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 symbolic
              links, regardless of the form of PATH.

              Write debugging information about pruning decisions to standard error output.

       -h, --help
              Write a summary of the available options to standard output and exit successfully.

       -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 configuration file.

       --prunefs FS
              Set PRUNEFS to FS, overriding the configuration file.

       --prunenames NAMES
              Set PRUNENAMES to NAMES, overriding the configuration file.

       --prunepaths PATHS
              Set PRUNEPATHS to PATHS, overriding the configuration 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, or if the database file is readable by "others" or it is not
              owned by plocate, 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  plocate
              and  the  database  permissions  prohibit reading the database by users using other
              means than locate(1), which is set-gid plocate.

              Note that the visibility flag is checked only if the database is owned  by  plocate
              and it is not readable by "others".

       -v, --verbose
              Output path names of files to standard output, as soon as they are found.

       -V, --version
              Write  information  about  the version and license of locate on standard output and
              exit successfully.


       To create a private plocate database as a user other than root, run
              updatedb -l 0 -o db_file -U source_directory
       Note that all users that can read db_file can get  the  complete  list  of  files  in  the
       subtree of source_directory.


              A  configuration  file.  See updatedb.conf(5).  Uses exactly the same format as the
              one used by mlocate(1)'s updatedb, so they can be shared.

              The database updated by default.


       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.
