This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

|
.Sh DESCRIPTION
|
|
The
|
|
.Nm whereis
|
|
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 of the form
|
|
.Ql .ext ,
|
|
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 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 EXAMPLE
|
|
The following finds all utilities under
|
|
.Pa /usr/bin
|
|
that do not have documentation:
|
|
.Dl whereis -m -u /usr/bin/*
|
|
.Sh SEE ALSO
|
|
.Xr locate 1 ,
|
|
.Xr man 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 HISTORY
|
|
The
|
|
.Nm whereis
|
|
command appeared in
|
|
.Bx 3.0 .
|
|
This version re-implements the historical
|
|
functionality that was lost in
|
|
.Bx 4.4 .
