.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 names are first stripped of leading path name
|
||||
components, any single trailing extension added by
|
||||
.Xr gzip 1
|
||||
or
|
||||
.Xr compress 1 ,
|
||||
and the leading
|
||||
.Ql s.\&
|
||||
or trailing
|
||||
.Ql ,v
|
||||
from a source code control system.
|
||||
utility checks the standard binary directories for the specified programs,
|
||||
printing out the paths of any it finds.
|
||||
.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 name
|
||||
list.
|
||||
.It Fl m
|
||||
Search for manual pages.
|
||||
.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.
|
||||
.El
|
||||
.Sh EXAMPLES
|
||||
The following finds all utilities under
|
||||
.Pa /usr/bin
|
||||
that do not have documentation:
|
||||
.Dl whereis -m -u /usr/bin/*
|
||||
string.
|
||||
If the
|
||||
.Op Fl p
|
||||
option is specified, then the value of the environment
|
||||
variable
|
||||
.Ev PATH
|
||||
is used instead.
|
||||
.Sh SEE ALSO
|
||||
.Xr find 1 ,
|
||||
.Xr locate 1 ,
|
||||
.Xr man 1 ,
|
||||
.Xr which 1 ,
|
||||
.Xr sysctl 8
|
||||
.Sh BUGS
|
||||
The search for sources is implemented as a quick search as the
|
||||
first-level subdirectory of each element of the list of source
|
||||
directories first. If this didn't succeed, the utility
|
||||
.Xr locate 1
|
||||
is requested to do the search in deeper nested subdirectories. This
|
||||
might take some time, and will only succeed if the locate database is
|
||||
up-to-date.
|
||||
.Sh COMPATIBILITY
|
||||
The historic flags and arguments for the
|
||||
.Nm
|
||||
utility are no longer available in this version.
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
command appeared in
|
||||
.Bx 3.0 .
|
||||
This version re-implements the historical
|
||||
functionality that was lost in
|
||||
.Bx 4.4 .
