39.Dt WHEREIS 1
40.Os
41.Sh NAME
42.Nm whereis
43.Nd locate programs
44.Sh SYNOPSIS
45.Nm
46.Op Fl bmqsux
47.Op Fl BMS Ar dir Ar ... Fl f
48.Ar program ...
49.Sh DESCRIPTION
50The
51.Nm
52utility checks the standard binary, manual page, and source
53directories for the specified programs, printing out the paths of any
54it finds.  The supplied program names are first stripped of leading
55path name components, any single trailing extension added by
56.Xr gzip 1 ,
57.Xr compress 1 ,
58or
59.Xr bzip2 1 ,
60and the leading
61.Ql s.\&
62or trailing
63.Ql ,v
64from a source code control system.
65.Pp
66The default path searched is the string returned by the
67.Xr sysctl 8
68utility for the
69.Dq user.cs_path
70string, with
71.Pa /usr/libexec ,
72.Pa /usr/games
73and the current user's
74.Ev $PATH
75appended.  Manual pages are searched by default along the
76.Ev $MANPATH .
77Program sources are located in a list of known standard places,
78including all the subdirectories of
79.Pa /usr/src
80and
81.Pa /usr/ports .
82.Pp
83The following options are available:
84.Bl -tag -width indent
85.It Fl B
86Specify directories to search for binaries.  Requires the
87.Fl f
88option.
89.It Fl M
90Specify directories to search for manual pages.  Requires the
91.Fl f
92option.
93.It Fl S
94Specify directories to search for program sources.  Requires the
95.Fl f
96option.
97.It Fl b
98Search for binaries.
99.It Fl f
100Delimits the list of directories after the
101.Fl B ,
102.Fl M ,
103or
104.Fl S
105options, and indicates the beginning of the
106.Ar program
107list.
108.It Fl m
109Search for manual pages.
110.It Fl q
111.Pq Dq quiet .
112Suppress the output of the utility name in front of the normal
113output line.
114This can become handy for use in a backquote substitution of a
115shell command line, see
116.Sx EXAMPLES .
117.It Fl s
118Search for source directories.
119.It Fl u
120Search for
121.Dq unusual
122entries.  A file is said to be unusual if it does not have one entry
123of each requested type.
124Only the name of the unusual entry is printed.
125.It Fl x
126Do not use
127.Dq expensive
128tools when searching for source directories.
129Normally, after unsuccessfully searching all the first-level
130subdirectories of the source directory list,
131.Nm
132will ask
133.Xr locate 1
134to find the entry on its behalf.
135Since this can take much longer, it can be turned off with
136.Fl x .
137.El
138.Sh EXAMPLES
139The following finds all utilities under
140.Pa /usr/bin
141that do not have documentation:
142.Pp
143.Dl whereis -m -u /usr/bin/*
144.Pp
145Change to the source code directory of
146.Xr ls 1 :
147.Pp
148.Dl cd `whereis -sq ls`
149.Sh SEE ALSO
150.Xr find 1 ,
151.Xr locate 1 ,
152.Xr man 1 ,
153.Xr which 1 ,
154.Xr sysctl 8
155.Sh HISTORY
156The
157.Nm
158utility appeared in
159.Bx 3.0 .
160This version re-implements the historical
161functionality that was lost in
162.Bx 4.4 .
163.Sh AUTHORS
164This implementation of the
165.Nm
166command was written by
167.An J\(:org Wunsch .
168.Sh BUGS
169This re-implementation of the
170.Nm
171utility is not bug-for-bug compatible with historical versions.
172It is believed to be compatible with the version that was shipping with
173.Fx 2.2
174through
175.Fx 4.5
176though.
