|
|
.Nm
|
|
.Op Fl bmqsux
|
|
.Op Fl BMS Ar dir Ar ... Fl f
|
|
.Ar program ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility checks the standard binary, manual page, and source
|
|
directories for the specified programs, printing out the paths of any
|
|
it finds. The supplied program names are first stripped of leading
|
|
path name components, any single trailing extension added by
|
|
.Xr gzip 1 ,
|
|
.Xr compress 1 ,
|
|
or
|
|
.Xr bzip2 1 ,
|
|
and the leading
|
|
.Ql s.\&
|
|
or trailing
|
|
.Ql ,v
|
|
from a source code control system.
|
|
.Pp
|
|
The default path searched is the string returned by the
|
|
.Xr sysctl 8
|
|
utility for the
|
|
.Dq user.cs_path
|
|
string, with
|
|
.Pa /usr/libexec
|
|
and the current user's
|
|
.Ev $PATH
|
|
appended. Manual pages are searched by default along the
|
|
.Ev $MANPATH .
|
|
Program sources are located in a list of known standard places,
|
|
including all the subdirectories of
|
|
.Pa /usr/src
|
|
and
|
|
.Pa /usr/ports .
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width indent
|
|
.It Fl B
|
|
Specify directories to search for binaries. Requires the
|
|
.Fl f
|
|
option.
|
|
.It Fl M
|
|
Specify directories to search for manual pages. Requires the
|
|
.Fl f
|
|
option.
|
|
.It Fl S
|
|
Specify directories to search for program sources. Requires the
|
|
.Fl f
|
|
option.
|
|
.It Fl b
|
|
Search for binaries.
|
|
.It Fl f
|
|
Delimits the list of directories after the
|
|
.Fl B ,
|
|
.Fl M ,
|
|
or
|
|
.Fl S
|
|
options, and indicates the beginning of the
|
|
.Ar program
|
|
list.
|
|
.It Fl m
|
|
Search for manual pages.
|
|
.It Fl q
|
|
.Pq Dq quiet .
|
|
Suppress the output of the utility name in front of the normal
|
|
output line.
|
|
This can become handy for use in a backquote substitution of a
|
|
shell command line, see
|
|
.Sx EXAMPLES .
|
|
.It Fl s
|
|
Search for source directories.
|
|
.It Fl u
|
|
Search for
|
|
.Dq unusual
|
|
entries. A file is said to be unusual if it does not have one entry
|
|
of each requested type.
|
|
Only the name of the unusual entry is printed.
|
|
.It Fl x
|
|
Do not use
|
|
.Dq expensive
|
|
tools when searching for source directories.
|
|
Normally, after unsuccessfully searching all the first-level
|
|
subdirectories of the source directory list,
|
|
.Nm
|
|
will ask
|
|
.Xr locate 1
|
|
to find the entry on its behalf.
|
|
Since this can take much longer, it can be turned off with
|
|
.Fl x .
|
|
.El
|
|
.Sh EXAMPLES
|
|
The following finds all utilities under
|
|
.Pa /usr/bin
|
|
that do not have documentation:
|
|
.Pp
|
|
.Dl whereis -m -u /usr/bin/*
|
|
.Pp
|
|
Change to the source code directory of
|
|
.Xr ls 1 :
|
|
.Pp
|
|
.Dl cd `whereis -sq ls`
|
|
.Sh SEE ALSO
|
|
.Xr find 1 ,

.Xr locate 1 ,

|
.Xr man 1 ,

|
.Xr which 1 ,

.Xr sysctl 8

|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
utility appeared in
|
|
.Bx 3.0 .
|
|
This version re-implements the historical
|
|
functionality that was lost in
|
|
.Bx 4.4 .
|
|
.Sh AUTHORS
|
|
This implementation of the
|
|
.Nm
|
|
command was written by
|
|
.An J\(:org Wunsch .
|
|
.Sh BUGS
|
|
This re-implementation of the
|
|
.Nm
|
|
utility is not bug-for-bug compatible with historical versions.
|
|
It is believed to be compatible with the version that was shipping with
|
|
.Fx 2.2
|
|
through
|
|
.Fx 4.5
|
|
though.
