.SH NAME
|
|
pkg_info - a utility for getting information on software package distributions.
|
|
.SH SYNOPSIS
|
|
.na
|
|
.B pkg_info
|
|
.RB [options]
|
|
.RB "pkg-file|pkg-name\ [.. pkg-file|pkg-name]"
|
|
|
|
.SH DESCRIPTION
|
|
The
|
|
.B pkg_info
|
|
command is used to dump out information for packages, either packed up in
|
|
files or already installed on the system
|
|
with the
|
|
.B pkg_create
|
|
command.
|
|
|
|
.SH OPTIONS
|
|
.TP
|
|
The following command line options are supported.
|
|
.TP
|
|
.B \-a
|
|
Show all currently installed packages.
|
|
.TP
|
|
.B \-v
|
|
Turns on verbose output.
|
|
.TP
|
|
.B \-p
|
|
Show the installation prefix for each package.
|
|
.TP
|
|
.B \-c
|
|
Show the comment (one liner) field for each package.
|
|
.TP
|
|
.B \-d
|
|
Show the long description field for each package.
|
|
.TP
|
|
.B \-i
|
|
Show the install script (if any) for each package.
|
|
.TP
|
|
.B \-k
|
|
Show the de-install script (if any) for each package.
|
|
.TP
|
|
.B \-r
|
|
Show the requirements script (if any) for each package.
|
|
.TP
|
|
.BI "\-e\ " pkg-name
|
|
If the package identified by
|
|
.I pkg-name
|
|
is currently installed, return 0, otherwise return 1. This option
|
|
allows you to easily test for the presence of another (perhaps
|
|
prerequisite) package from a script.
|
|
.TP
|
|
.BI "\-l\ " str
|
|
Prefix each catagory of information shown with
|
|
.I str.
|
|
This is primarily of use to front-end programs who want to request a
|
|
lot of different information fields at once for a package, but don't
|
|
necessary want the output intermingled in such a way that they can't
|
|
organize it. This lets you add a special token to the start of
|
|
each field.
|
|
.BI "\-t\ " template
|
|
Use
|
|
.I template
|
|
as the input to mktemp(3). By default, this is the string
|
|
.B /tmp/instmp.XXXXXX
|
|
, but it may be necessary to override it in the situation where
|
|
space in your
|
|
.B /tmp
|
|
directory is limited. Be sure to leave some number of `X' characters
|
|
for mktemp(3) to fill in with a unique ID.
|
|
Note: This should really not be necessary with pkg_info,
|
|
since very little information is extracted from each package
|
|
and one would have to have a very small /tmp indeed to overflow
|
|
it.
|
|
.PP
|
|
.SH "TECHNICAL DETAILS"
|
|
Package info is either extracted from files supplied on the
|
|
command line, or from already installed package information
|
|
in /var/db/pkg/<pkg-name>.
|
|
.SH BUGS
|
|
Sure to be some.
