LOCATE(1)		FreeBSD	General	Commands Manual		     LOCATE(1)

     locate -- find filenames quickly

     locate [-0Scims] [-l limit] [-d database] pattern ...

     The locate	program	searches a database for	all pathnames which match the
     specified pattern.	 The database is recomputed periodically (usually
     weekly or daily), and contains the	pathnames of all files which are pub-
     licly accessible.

     Shell globbing and	quoting	characters (``*'', ``?'', ``\'', ``['' and
     ``]'') may	be used	in pattern, although they will have to be escaped from
     the shell.	 Preceding any character with a	backslash (``\'') eliminates
     any special meaning which it may have.  The matching differs in that no
     characters	must be	matched	explicitly, including slashes (``/'').

     As	a special case,	a pattern containing no	globbing characters (``foo'')
     is	matched	as though it were ``*foo*''.

     Historically, locate only stored characters between 32 and	127.  The cur-
     rent implementation store any character except newline (`\n') and NUL
     (`\0').  The 8-bit	character support does not waste extra space for plain
     ASCII file	names.	Characters less	than 32	or greater than	127 are	stored
     in	2 bytes.

     The following options are available:

     -0		 Print pathnames separated by an ASCII NUL character (charac-
		 ter code 0) instead of	default	NL (newline, character code

     -S		 Print some statistics about the database and exit.

     -c		 Suppress normal output; instead print a count of matching
		 file names.

     -d	database
		 Search	in database instead of the default file	name database.
		 Multiple -d options are allowed.  Each	additional -d option
		 adds the specified database to	the list of databases to be

		 The option database may be a colon-separated list of data-
		 bases.	 A single colon	is a reference to the default data-

		 $ locate -d $HOME/lib/mydb: foo

		 will first search string ``foo'' in $HOME/lib/mydb and	then
		 in /var/db/locate.database.

		 $ locate -d $HOME/lib/mydb::/cdrom/locate.database foo

		 will first search string ``foo'' in $HOME/lib/mydb and	then
		 in /var/db/locate.database and	then in

		       $ locate	-d db1 -d db2 -d db3 pattern

		 is the	same as

		       $ locate	-d db1:db2:db3 pattern


		       $ locate	-d db1:db2 -d db3 pattern

		 If - is given as the database name, standard input will be
		 read instead.	For example, you can compress your database
		 and use:

		 $ zcat	database.gz | locate -d	- pattern

		 This might be useful on machines with a fast CPU and little
		 RAM and slow I/O.  Note: you can only use one pattern for

     -i		 Ignore	case distinctions in both the pattern and the data-

     -l	number	 Limit output to number	of file	names and exit.

     -m		 Use mmap(2) instead of	the stdio(3) library.  This is the
		 default behavior and is faster	in most	cases.

     -s		 Use the stdio(3) library instead of mmap(2).

     LOCATE_PATH  path to the locate database if set and not empty, ignored if
		  the -d option	was specified.

     /var/db/locate.database	      locate database
     /usr/libexec/locate.updatedb     Script to	update the locate database
     /etc/periodic/weekly/310.locate  Script that starts the database rebuild

     find(1), whereis(1), which(1), fnmatch(3),	locate.updatedb(8)

     Woods, James A., "Finding Files Fast", ;login, 8:1, pp. 8-10, 1983.

     The locate	command	first appeared in 4.4BSD.  Many	new features were
     added in FreeBSD 2.2.

     The locate	program	may fail to list some files that are present, or may
     list files	that have been removed from the	system.	 This is because
     locate only reports files that are	present	in the database, which is typ-
     ically only regenerated once a week by the
     /etc/periodic/weekly/310.locate script.  Use find(1) to locate files that
     are of a more transitory nature.

     The locate	database is typically built by user ``nobody'' and the
     locate.updatedb(8)	utility	skips directories which	are not	readable for
     user ``nobody'', group ``nobody'',	or world.  For example,	if your	HOME
     directory is not world-readable, none of your files are in	the database.

     The locate	database is not	byte order independent.	 It is not possible to
     share the databases between machines with different byte order.  The cur-
     rent locate implementation	understands databases in host byte order or
     network byte order	if both	architectures use the same integer size.  So
     on	a FreeBSD/i386 machine (little endian),	you can	read a locate database
     which was built on	SunOS/sparc machine (big endian, net).

     The locate	utility	does not recognize multibyte characters.
