LOCATE(1)						    BSD General Commands Manual 						 LOCATE(1)

locate -- find files SYNOPSIS
locate [-d dbpath] pattern DESCRIPTION
locate searches a database for all pathnames which match the specified pattern. The database is recomputed periodically, and contains the pathnames of all files which are publicly 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*''. Options: -d dbpath Sets the list of databases to search to dbpath which can name one or more database files separated by ``:'', an empty component in the list represents the default database. The environment variable LOCATE_PATH has the same effect. EXIT STATUS
locate exits with a 0 if a match is found, and >0 if no match is found or if another problem (such as a missing or corrupted database file) is encountered. FILES
/var/db/locate.database Default database /usr/libexec/locate.updatedb Script to update database. SEE ALSO
find(1), fnmatch(3), weekly.conf(5) Woods, James A., "Finding Files Fast", ;login, 8:1, pp. 8-10, 1983. HISTORY
The locate command appeared in 4.4BSD. BSD
April 5, 2003 BSD
