non-backward compatible changes in the format of packing list and handle them gracefully; - fix a longstanding issue with symlinks handling. Instead of recording checksum for the file symlink points to, record checksum for the value returned by readlink(2). For backward compatibility increase packing list format minor version number and provide a fallback to a previous behaviour, if package in question was created with older version of pkg_* tools; Submitted by: Alec Wolman <wolman@cs.washington.edu>, sobomax - don't record MD5 checksum for device nodes, fifo's and other non-regular files.

.Os
|

.Sh NAME
|
|
.Nm pkg_info
|
|
.Nd a utility for displaying information on software packages
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl cdDfgGiIkLmopqrRsvVx
|
|
.Op Fl e Ar package
|
|
.Op Fl l Ar prefix
|
|
.Op Fl t Ar template

.Fl a
|
|
.Op Ar flags
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command is used to dump out information for packages, either packed up in
|
|
files with the
|
|
.Xr pkg_create 1
|
|
command or already installed on the system
|
|
with the
|
|
.Xr pkg_add 1
|
|
command.
|
|
.Sh OPTIONS
|
|
The following command line options are supported:
|
|
.Bl -tag -width indent
|
|
.It Ar pkg-name ...
|
|
The named packages are described. A package name may either be the name of
|
|
an installed package, the pathname to a package distribution file or a
|
|
URL to an FTP available package.
|
|
.It Fl a
|
|
Show all currently installed packages.
|
|
.It Fl v
|
|
Turn on verbose output.
|
|
.It Fl p
|
|
Show the installation prefix for each package.
|
|
.It Fl q
|
|
Be
|
|
.Dq quiet
|
|
in emitting report headers and such, just dump the
|
|
raw info (basically, assume a non-human reading).
|
|
.It Fl c
|
|
Show the (one line) comment field for each package.
|
|
.It Fl d
|
|
Show the long description field for each package.
|
|
.It Fl D
|
|
Show the install-message file for each package.
|
|
.It Fl f
|
|
Show the packing list instructions for each package.
|
|
.It Fl g
|
|
Show files that don't match the recorded checksum.
|
|
.It Fl i
|
|
Show the install script (if any) for each package.
|
|
.It Fl I
|
|
Show an index line for each package. This option takes
|
|
precedence over all other package formatting options.
|
|
.It Fl k
|
|
Show the de-install script (if any) for each package.
|
|
.It Fl r
|
|
Show the requirements script (if any) for each package.
|
|
.It Fl R
|
|
Show the list of installed packages which require each package.
|
|
.It Fl m
|
|
Show the mtree file (if any) for each package.
|
|
.It Fl L
|
|
Show the files within each package. This is different from just
|
|
viewing the packing list, since full pathnames for everything
|
|
are generated.
|
|
.It Fl s
|
|
Show the total size occupied by files installed within each package.
|
|
.It Fl o
|
|
Show the
|
|
.Dq origin
|
|
path recorded on package generation. This path
|
|
intended to give an idea as to where the underlying port, from which
|
|
package was generated, is located in the
|
|
.Fx
|
|
.Em "Ports Collection" .
|
|
.It Fl G
|
|
Do not try to expand shell glob patterns in the
|
|
.Ar pkg-name
|
|
when selecting packages to be displayed (by default
|
|
.Nm
|
|
automatically expands shell glob patterns in the
|
|
.Ar pkg-name ) .
|
|
.It Fl W
|
|
For the specified
|
|
.Ar filename
|
|
argument show which package it belongs to. If the file is not in the
|
|
current directory, and does not have an absolute path, then the
|
|
.Ev PATH
|
|
is searched using
|
|
.Xr which 1 .
|
|
.It Fl x
|
|
Treat the
|
|
.Ar pkg-name
|
|
as a regular expression and display information only for packages
|
|
whose names match that regular expression. Multiple regular
|
|
expressions could be provided, in that case
|
|
.Nm
|
|
displays information about all packages that match at least one
|
|
regular expression from the list.
|
|
.It Fl e Ar pkg-name
|
|
If the package identified by
|
|
.Ar 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.
|
|
.It Fl l Ar str
|
|
Prefix each information category header (see
|
|
.Fl q )
|
|
shown with
|
|
.Ar 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.
|
|
.It Fl t Ar template
|
|
Use
|
|
.Ar template
|
|
as the input to
|
|
.Xr mktemp 3
|
|
when creating a
|
|
.Dq staging area .
|
|
By default, this is the string
|
|
.Pa /tmp/instmp.XXXXXX ,
|
|
but it may be necessary to override it in the situation where
|
|
space in your
|
|
.Pa /tmp
|
|
directory is limited. Be sure to leave some number of `X' characters
|
|
for
|
|
.Xr mktemp 3
|
|
to fill in with a unique ID.
|
|
.Bd -ragged -offset indent -compact
|
|
Note: This should really not be necessary with
|
|
.Nm ,
|
|
since very little information is extracted from each package
|
|
and one would have to have a very small
|
|
.Pa /tmp
|
|
indeed to overflow it.
|
|
.Ed
|
|
.It Fl V
|
|
Show revision number of the packing list format.
|
|
.El
|
|
.Sh TECHNICAL DETAILS
|
|
Package info is either extracted from package files named on the
|
|
command line, or from already installed package information
|
|
in
|
|
.Pa /var/db/pkg/ Ns Aq Ar pkg-name .
|
|
.Sh ENVIRONMENT
|
|
.Ev PKG_TMPDIR
|
|
points to the directory where
|
|
.Nm
|
|
creates its temporary files.
|
|
If this variable is not set,
|
|
.Ev TMPDIR
|
|
is used. If both are unset, the builtin defaults are used.
|
|
.Pp
|
|
.Ev PKG_DBDIR
|
|
specifies an alternative location for the installed package database.
|
|
.Sh FILES
|
|
.Bl -tag -width /var/db/pkg -compact
|
|
.It Pa /var/tmp
|
|
Used if the environment variables
|
|
.Ev PKG_TMPDIR
|
|
and
|
|
.Ev TMPDIR
|
|
are not set, or if the directories named have insufficient space.
|
|
.It Pa /tmp
|
|
The next choice if
|
|
.Pa /var/tmp
|
|
does not exist or has insufficient space.
|
|
.It Pa /usr/tmp
|
|
The last choice if
|
|
.Pa /tmp
|
|
is unsuitable.
|
|
.It Pa /var/db/pkg
|
|
Default location of the installed package database.
