33.Dt WHEREIS 1
34.Os
35.Sh NAME
36.Nm whereis
37.Nd locate programs
38.Sh SYNOPSIS
39.Nm
40.Op Fl abmqsux
41.Op Fl BMS Ar dir ... Fl f
42.Ar program ...
43.Sh DESCRIPTION
44The
45.Nm
46utility checks the standard binary, manual page, and source
47directories for the specified programs, printing out the paths of any
48it finds.
49The supplied program names are first stripped of leading
50path name components, any single trailing extension added by
51.Xr gzip 1 ,
52.Xr compress 1 ,
53or
54.Xr bzip2 1 ,
55and the leading
56.Ql s.\&
57or trailing
58.Ql ,v
59from a source code control system.
60.Pp
61The default path searched is the string returned by the
62.Xr sysctl 8
63utility for the
64.Dq user.cs_path
65string, with
66.Pa /usr/libexec
67and the current user's
68.Ev $PATH
69appended.
70Manual pages are searched by default along the
71.Ev $MANPATH .
72Program sources are located in a list of known standard places,
73including all the subdirectories of
74.Pa /usr/src
75and
76.Pa /usr/ports .
77.Pp
78The following options are available:
79.Bl -tag -width indent
80.It Fl B
81Specify directories to search for binaries.
82Requires the
83.Fl f
84option.
85.It Fl M
86Specify directories to search for manual pages.
87Requires the
88.Fl f
89option.
90.It Fl S
91Specify directories to search for program sources.
92Requires the
93.Fl f
94option.
95.It Fl a
96Report all matches instead of only the first of each requested type.
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.
123A file is said to be unusual if it does not have at least
124one entry of each requested type.
125Only the name of the unusual entry is printed.
126.It Fl x
127Do not use
128.Dq expensive
129tools when searching for source directories.
130Normally, after unsuccessfully searching all the first-level
131subdirectories of the source directory list,
132.Nm
133will ask
134.Xr locate 1
135to find the entry on its behalf.
136Since this can take much longer, it can be turned off with
137.Fl x .
138.El
139.Sh EXAMPLES
140The following finds all utilities under
141.Pa /usr/bin
142that do not have documentation:
143.Pp
144.Dl whereis -m -u /usr/bin/*
145.Pp
146Change to the source code directory of
147.Xr ls 1 :
148.Pp
149.Dl cd `whereis -sq ls`
150.Sh SEE ALSO
151.Xr find 1 ,
152.Xr locate 1 ,
153.Xr man 1 ,
154.Xr which 1 ,
155.Xr sysctl 8
156.Sh HISTORY
157The
158.Nm
159utility appeared in
160.Bx 3.0 .
161This version re-implements the historical
162functionality that was lost in
163.Bx 4.4 .
164.Sh AUTHORS
165This implementation of the
166.Nm
167command was written by
168.An J\(:org Wunsch .
169.Sh BUGS
170This re-implementation of the
171.Nm
172utility is not bug-for-bug compatible with historical versions.
173It is believed to be compatible with the version that was shipping with
174.Fx 2.2
175through
176.Fx 4.5
177though.
178.Pp
179The
180.Nm
181utility can report some unrelated source entries when the
182.Fl a
183option is specified.
