SYNOPSIS
[-abmqsux
]
[-BMS dir ... -f
]
program ...
DESCRIPTION
The
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
gzip(1),
compress(1),
or
bzip2(1),
and the leading
`s.'
or trailing
`,v'
from a source code control system.
The default path searched is the string returned by the
sysctl(8)
utility for the
``user.cs_path''
string, with
/usr/libexec
/usr/games
and the current user's
$PATH
appended.
Manual pages are searched by default along the
$MANPATH
Program sources are located in a list of known standard places,
including all the subdirectories of
/usr/src
and
/usr/ports
The following options are available:
-B
Specify directories to search for binaries.
Requires the
-f
option.
-M
Specify directories to search for manual pages.
Requires the
-f
option.
-S
Specify directories to search for program sources.
Requires the
-f
option.
-a
Report all matches instead of only the first of each requested type.
-b
Search for binaries.
-f
Delimits the list of directories after the
-B
-M
or
-S
options, and indicates the beginning of the
program
list.
-m
Search for manual pages.
-q
(``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 .
-s
Search for source directories.
-u
Search for
``unusual''
entries.
A file is said to be unusual if it does not have at least
one entry of each requested type.
Only the name of the unusual entry is printed.
-x
Do not use
``expensive''
tools when searching for source directories.
Normally, after unsuccessfully searching all the first-level
subdirectories of the source directory list,
will ask
locate(1)
to find the entry on its behalf.
Since this can take much longer, it can be turned off with
-x
EXAMPLES
The following finds all utilities under
/usr/bin
that do not have documentation:
The
utility appeared in
BSD 3.0
This version re-implements the historical
functionality that was lost in
BSD 4.4
AUTHORS
This implementation of the
command was written by
An J:org Wunsch .
BUGS
This re-implementation of the
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.
The
utility can report some unrelated source entries when the
-a
option is specified.
