1. NAME

locate - find files by name

2. SYNOPSIS

locate [OPTION]... PATTERN...

3. DESCRIPTION

locate reads one or more databases prepared by

R 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 PATTERNcontains no globbing characters,

locate behaves as if the pattern were \fB*PATTERN\fB*. By default,

locate does not check whether files found in database still exist.

locate can never report files created after the most recent update of the relevant database.

4. 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.

5. OPTIONS

  • -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, \fB--database DBPATH
        Replace the default database with DBPATH. DBPATHis 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 LIMITentries. 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

R 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 licence 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.

6. EXAMPLES

To search for a file named exactly NAME(not \fB*NAME\fB*), use

locate -b \fB'\\NAME\fB' Because \\ is a globbing character, this disables the implicit replacement of NAMEby \fB*NAME\fB*.

7. FILES

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

8. ENVIRONMENT

  • LOCATE_PATH
        Path to additional databases, added after the default database or the databases specified using the

--database option.

9. 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.
