locate(1)                    General Commands Manual                   locate(1)



NAME
       locate - find files by name


SYNOPSIS
       locate [OPTION]... PATTERN...


DESCRIPTION
       locate reads one or more databases prepared by updatedb(8) and writes
       file names matching at least one of the PATTERNs to standard output, one
       per line.

       If --regex is not specified, PATTERNs can contain globbing characters.
       If any PATTERN contains no globbing characters, locate behaves as if the
       pattern were *PATTERN*.

       By default, locate does not check whether files found in database still
       exist (but it does require all parent directories to exist if the
       database was built with --require-visibility no).  locate can never
       report files created after the most recent update of the relevant
       database.


EXIT STATUS
       locate exits with status 0 if any match was found or if locate was
       invoked with one of the --limit 0, --help, --statistics or --version
       options.  If no match was found or a fatal error was encountered, locate
       exits with status 1.

       Errors encountered while reading a database are not fatal, search
       continues in other specified databases, if any.


OPTIONS
       -A, --all
              Print only entries that match all PATTERNs instead of requiring
              only one of them to match.


       -b, --basename
              Match only the base name against the specified patterns.  This is
              the opposite of --wholename.


       -c, --count
              Instead of writing file names on standard output, write the number
              of matching entries only.


       -d, --database DBPATH
              Replace the default database with DBPATH.  DBPATH is a :-separated
              list of database file names.  If more than one --database option
              is specified, the resulting path is a concatenation of the
              separate paths.

              An empty database file name is replaced by the default database.
              A database file name - refers to the standard input.  Note that a
              database can be read from the standard input only once.


       -e, --existing
              Print only entries that refer to files existing at the time locate
              is run.


       -L, --follow
              When checking whether files exist (if the --existing option is
              specified), follow trailing symbolic links.  This causes broken
              symbolic links to be omitted from the output.

              This is the default behavior.  The opposite can be specified using
              --nofollow.


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


       -i, --ignore-case
              Ignore case distinctions when matching patterns.


       -l, --limit, -n LIMIT
              Exit successfully after finding LIMIT entries.  If the --count
              option is specified, the resulting count is also limited to LIMIT.


       -m, --mmap
              Ignored, for compatibility with BSD and GNU locate.


       -P, --nofollow, -H
              When checking whether files exist (if the --existing option is
              specified), do not follow trailing symbolic links.  This causes
              broken symbolic links to be reported like other files.

              This is the opposite of --follow.


       -0, --null
              Separate the entries on output using the ASCII NUL character
              instead of writing each entry on a separate line.  This option is
              designed for interoperability with the --null option of GNU
              xargs(1).


       -S, --statistics
              Write statistics about each read database to standard output
              instead of searching for files and exit successfully.


       -q, --quiet
              Write no messages about errors encountered while reading and
              processing databases.


       -r, --regexp REGEXP
              Search for a basic regexp REGEXP.  No PATTERNs are allowed if this
              option is used, but this option can be specified multiple times.


       --regex
              Interpret all PATTERNs as extended regexps.


       -s, --stdio
              Ignored, for compatibility with BSD and GNU locate.


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


       -w, --wholename
              Match only the whole path name against the specified patterns.

              This is the default behavior.  The opposite can be specified using
              --basename.


EXAMPLES
       To search for a file named exactly NAME (not *NAME*), use
              locate -b '\NAME'
       Because \ is a globbing character, this disables the implicit replacement
       of NAME by *NAME*.


FILES
       /var/lib/mlocate/mlocate.db
              The database searched by default.


ENVIRONMENT
       LOCATE_PATH
              Path to additional databases, added after the default database or
              the databases specified using the --database option.


NOTES
       The order in which the requested databases are processed is unspecified,
       which allows locate to reorder the database path for security reasons.

       locate attempts to be compatible to slocate (without the options used for
       creating databases) and GNU locate, in that order.  This is the reason
       for the impractical default --follow option and for the confusing set of
       --regex and --regexp options.

       The short spelling of the -r option is incompatible to GNU locate, where
       it corresponds to the --regex option.  Use the long option names to avoid
       confusion.

       The LOCATE_PATH environment variable replaces the default database in BSD
       and GNU locate, but it is added to other databases in this implementation
       and slocate.
