-0, --null
       Use ASCII NUL as a separator, instead of newline.

-A, --all
       Print  only  names which match all non-option arguments, not those matching one or more non-option
       arguments.

-b, --basename
       Results are considered to match if the pattern specified matches the final component of  the  name
       of  a  file  as  listed in the database.  This final component is usually referred to as the `base
       name'.

-c, --count
       Instead of printing the matched filenames, just print the total number of matches we found, unless
       --print (-p) is also present.

-d path, --database=path
       Instead of searching the default file name database, search the file name databases in path, which
       is a colon-separated list of database file names.  You  can  also  use  the  environment  variable
       LOCATE_PATH  to  set  the  list of database files to search.  The option overrides the environment
       variable if both are used.  Empty elements in the path are taken to be synonyms for the file  name
       of the default database.  A database can be supplied on stdin, using `-' as an element of path. If
       more than one element of path is `-', later instances  are  ignored  (and  a  warning  message  is
       printed).

       The  file  name  database  format  changed  starting with GNU find and locate version 4.0 to allow
       machines with different byte orderings to  share  the  databases.   This  version  of  locate  can
       automatically  recognize  and  read  databases  produced  for older versions of GNU locate or Unix
       versions of locate or find.  Support for the old locate database format will be discontinued in  a
       future release.

-e, --existing
       Only  print  out  such  names  that  currently  exist (instead of such names that existed when the
       database was created).  Note that this may slow down the program a lot, if there are many  matches
       in  the  database.  If you are using this option within a program, please note that it is possible
       for the file to be deleted after locate has checked that it exists, but before you use it.

-E, --non-existing
       Only print out such names that currently do not exist (instead of such names that existed when the
       database  was created).  Note that this may slow down the program a lot, if there are many matches
       in the database.

--help Print a summary of the options to locate and exit.

-i, --ignore-case
       Ignore case distinctions in both the pattern and the file names.

-l N, --limit=N
       Limit the number of matches to N.  If a limit is set  via  this  option,  the  number  of  results
       printed for the -c option will never be larger than this number.

-L, --follow
       If  testing for the existence of files (with the -e or -E options), consider broken symbolic links
       to be non-existing.   This is the default.

--max-database-age D
       Normally, locate will issue a warning message when it searches a database which  is  more  than  8
       days  old.   This option changes that value to something other than 8.  The effect of specifying a
       negative value is undefined.

-m, --mmap
       Accepted but does nothing, for compatibility with BSD locate.

-P, -H, --nofollow
       If testing for the existence of files (with the -e or -E options), treat broken symbolic links  as
       if  they  were  existing files.  The -H form of this option is provided purely for similarity with
       find; the use of -P is recommended over -H.

-p, --print
       Print search results when they normally would not, because of the presence of --statistics (-S) or
       --count (-c).

-r, --regex
       The  pattern specified on the command line is understood to be a regular expression, as opposed to
       a glob pattern.  The Regular expressions work in the same was as in emacs and find, except for the
       fact  that  "."  will  match  a  newline.   Filenames whose full paths match the specified regular
       expression are printed (or, in the case of the -c option, counted).  If you wish  to  anchor  your
       regular  expression  at the ends of the full path name, then as is usual with regular expressions,
       you should use the characters ^ and $ to signify this.

-s, --stdio
       Accepted but does nothing, for compatibility with BSD locate.

-S, --statistics
       Print various statistics about each locate database and then exit  without  performing  a  search,
       unless  non-option  arguments  are given.  For compatibility with BSD, -S is accepted as a synonym
       for  --statistics.   However,  the  ouptut  of  locate  -S  is  different  for  the  GNU  and  BSD
       implementations of locate.

--version
       Print the version number of locate and exit.

-w, --wholename
       Match against the whole name of the file as listed in the database.  This is the default.
