39.Dt WHEREIS 1
40.Os
41.Sh NAME
42.Nm whereis
43.Nd locate programs
44.Sh SYNOPSIS
45.Nm
46.Op Fl abmqsux
47.Op Fl BMS Ar dir ... 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 a
98Report all matches instead of only the first of each requested type.
99.It Fl b
100Search for binaries.
101.It Fl f
102Delimits the list of directories after the
103.Fl B ,
104.Fl M ,
105or
106.Fl S
107options, and indicates the beginning of the
108.Ar program
109list.
110.It Fl m
111Search for manual pages.
112.It Fl q
113.Pq Dq quiet .
114Suppress the output of the utility name in front of the normal
115output line.
116This can become handy for use in a backquote substitution of a
117shell command line, see
118.Sx EXAMPLES .
119.It Fl s
120Search for source directories.
121.It Fl u
122Search for
123.Dq unusual
124entries.  A file is said to be unusual if it does not have at least
125one entry of each requested type.
126Only the name of the unusual entry is printed.
127.It Fl x
128Do not use
129.Dq expensive
130tools when searching for source directories.
131Normally, after unsuccessfully searching all the first-level
132subdirectories of the source directory list,
133.Nm
134will ask
135.Xr locate 1
136to find the entry on its behalf.
137Since this can take much longer, it can be turned off with
138.Fl x .
139.El
140.Sh EXAMPLES
141The following finds all utilities under
142.Pa /usr/bin
143that do not have documentation:
144.Pp
145.Dl whereis -m -u /usr/bin/*
146.Pp
147Change to the source code directory of
148.Xr ls 1 :
149.Pp
150.Dl cd `whereis -sq ls`
151.Sh SEE ALSO
152.Xr find 1 ,
153.Xr locate 1 ,
154.Xr man 1 ,
155.Xr which 1 ,
156.Xr sysctl 8
157.Sh HISTORY
158The
159.Nm
160utility appeared in
161.Bx 3.0 .
162This version re-implements the historical
163functionality that was lost in
164.Bx 4.4 .
165.Sh AUTHORS
166This implementation of the
167.Nm
168command was written by
169.An J\(:org Wunsch .
170.Sh BUGS
171This re-implementation of the
172.Nm
173utility is not bug-for-bug compatible with historical versions.
174It is believed to be compatible with the version that was shipping with
175.Fx 2.2
176through
177.Fx 4.5
178though.
179.Pp
180The
181.Nm
182utility can report some unrelated source entries when the
183.Fl a
184option is specified.
