.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
script displays version numbers for system components.
|
|
It is useful for finding out the installed versions of
|
|
the components of a system.
|
|
The
|
|
.Nm
|
|
utility uses a combination of ways to retrieve version
|
|
information from the installed utilities.
|
|
.Sh OPTIONS
|
|
The following options are available:
|
|
.Bl -tag -width inits
|
|
.It Fl d
|
|
This option provides a destination directory, used
|
|
as the root directory of an alternative set of programs
|
|
and libraries.
|
|
This can be useful for finding versions of utilities
|
|
and libraries rooted in the file system directory,
|
|
such as the destination directory from a
|
|
.Dv build.sh
|
|
run.
|
|
.It Fl L
|
|
Give a list of directories
|
|
.Pq "colon separated"
|
|
that are used when searching for libraries.
|
|
If not given the value of
|
|
.Ev LD_LIBRARY_PATH
|
|
is used if set in the environment, or otherwise
|
|
a standard (built-in) set of directories.
|
|
.It Fl P
|
|
Set
|
|
.Ev PATH .
|
|
If not given, the system default path, as obtained from
|
|
.Ic user.cs_path
|
|
via
|
|
.Xr sysctl 8
|
|
is used.
|
|
To use the current value of $PATH from the caller, use:
|
|
.Dl -P \*q$PATH\*q
|
|
.It Fl v
|
|
Show the commands used to obtain the version information
|
|
for each component
|
|
.El
|
|
.Pp
|
|
Arguments may be given to
|
|
.Nm .
|
|
If any arguments are specified, they are assumed
|
|
to be names of programs, or shared libraries,
|
|
installed on the system.
|
|
If no arguments are provided, then all of the
|
|
items that are known to
|
|
.Nm
|
|
are reported.
|
|
.Sh EXIT STATUS
|
|
.Nm
|
|
