behavior.
Like
-.BR mlocate(1),
+.BR mlocate (1),
+.B plocate
shows all files visible to the calling user (by virtue of
having read and execute permissions on all parent directories),
and none that are not, by means of running with the setgid
testing visibility as the calling user.
.SH OPTIONS
+.TP
+\fB\-b\fR, \fB\-\-basename\fR
+Match only against the file name portion of the path name,
+ie., the directory names will be excluded from the match
+(but still printed). This does not speed up the search,
+but can suppress uninteresting matches.
+
.TP
\fB\-c\fR, \fB\-\-count\fR
Do not print each match. Instead, count them, and print out a total
.TP
\fB\-d\fR, \fB\-\-database\fR \fIDBPATH\fR
-Find matches in \fB/var/lib/mlocate/plocate.db\fR, instead of the given database.
-(
-.B plocate
-does not currently support multiple databases.)
+Find matches in the given database, instead of \fB/var/lib/plocate/plocate.db\fR.
+This argument can be given multiple times, to search multiple databases.
+It is also possible to give multiple databases in one argument, separated by
+.BR : .
+(Any character, including : and \\, can be escaped by prepending a \\.)
+
+.TP
+\fB\-e\fR, \fB\-\-existing\fR
+Print only entries that refer to files existing at the time
+.B locate
+is run. Note that unlike
+.BR mlocate (1),
+symlinks are not followed by default (and indeed, there is no option
+to change this).
.TP
\fB\-i\fR, \fB\-\-ignore\-case\fR
\fB\-r\fR, \fB\-\-regexp\fR
Patterns are taken to be POSIX basic regular expressions.
See
-.BR regex(7)
+.BR regex (7)
for more information. Note that this forces a linear scan
through the entire database, which is slow.
.I extended
regular expressions.
+.TP
+\fB\-w\fR, \fB\-\-wholename\fR
+Match against the entire path name. This is the default,
+so unless \fB-b\fR is given first (see above), it will not do
+anything. This option thus exists only as compatibility with
+.BR mlocate (1).
+
.TP
.B \-\-help
Print out usage information, then exit successfully.
.B \-\-version
Print out version information, then exit successfully.
+.SH ENVIRONMENT
+
+.TP
+\fBLOCATE_PATH\fR
+If given, appended after the list of \fB\-\-database\fR paths
+(whether an explicit is given or the default is used).
+Colon-delimiting and character escaping follows the same rules
+as for \fB\-\-database\fR.
