Complete rewrite, once again.
This is basically a ``C compilation'' of the former whereis.pl file, employing the same algorithms, and aiming at being mostly UI-compatible to the old (legally tainted) 4.3BSD whereis(1). In comparision, the 4.4BSD-Lite version is just another variant of which(1) only, where in particular the option to search for source directories is sorely missing. While i was at it, i added two more options which i contemplated doing long since. -x will suppress the run of locate(1) to find sources that could not be found otherwise, potentially saving a lot of time (but obviously, risking to not find some sources that are well hidden in the tree). -q will omit the leading name of the query, so in particular, you can now do something like: cd `whereis -qs ls` I'd explicitly like to thank johan for his review which was quite a bit more than an average review, including sending me a lot of diffs.

|

|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
utility checks the standard binary directories for the specified programs,
|
||||
printing out the paths of any it finds.
|
||||
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.
|
||||
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 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 .
|
||||
.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.
