PKG_INFO(1)                  BSD Reference Manual                  PKG_INFO(1)

NAME

     pkg_info - display information on software packages

SYNOPSIS

     pkg_info [-cDdfIikLmPpqRrvh] [-e package] [-l prefix] pkg-name [...]
     pkg_info [-a flags]

DESCRIPTION

     The pkg_info command is used to dump out information for packages, which
     may be either packed up in files or already installed on the system with
     the pkg_create(1) command.

     The pkg-name may be the name of an installed package, the pathname to a
     package distribution file, or a URL to an ftp-available package. pkg_info
     will try to complete pkg-name with a version number while looking through
     installed packages.

     The following command-line options are supported:

     -a      Show information for all currently installed packages.

     -c      Show the one-line comment field for each package.

     -D      Show the install-message file (if any) for each package.

     -d      Show the long-description field for each package.

     -e pkg-name
             This option allows you to test for the presence of another
             (perhaps prerequisite) package from a script. If the package
             identified by pkg-name is currently installed, return 0, other-
             wise return 1. In addition, the names of any package(s) found in-
             stalled are printed to stdout unless turned off using the -q op-
             tion.

             If the given pkg-name contains a shell meta-character, it will be
             matched against all installed packages using fnmatch(3). csh(1)
             style "{,}" alternates have also been implemented in addition to
             this. Package version numbers can also be matched in a relational
             manner using the ">=", "<=", ">", and "<" operators. For example,
             pkg_info -e 'name->=1.3' will match versions 1.3 and later of the
             name package.

     -f      Show the packing list instructions for each package.

     -I      Show the index entry for each package.

     -i      Show the install script (if any) for each package.

     -k      Show the de-install script (if any) for each package.

     -L      Show the files within each package. This is different from just
             viewing the packing list, since full pathnames for everything are
             generated.

     -l str  Prefix each information category header (see -q) shown with str.
             This is primarily of use to front-end programs that want to re-
             quest a lot of different information fields at once for a pack-
             age, but don't necessary want the output intermingled in such a
             way that they can't organize it. This lets you add a special to-
             ken to the start of each field.

     -m      Show the mtree file (if any) for each package.

     -P      Show a list of packages that the package depends on.

     -p      Show the installation prefix for each package.

     -q      Be "quiet" in emitting report headers and such, just dump the raw
             info (basically, assume a non-human reading).

     -R      Show which packages require a given package.

     -r      Show the requirements script (if any) for each package.

     -s      Show installation of configuration files (samples) for each pack-
             age.

     -v      Turn on verbose output.

ENVIRONMENT

     PKG_DBDIR  The standard package database directory, /var/db/pkg, can be
                overridden by specifying an alternative directory in the
                PKG_DBDIR environment variable.

     PKG_PATH   This can be used to specify a colon-separated list of paths to
                search for package files. The current directory is always
                searched first, even if PKG_PATH is set. If PKG_PATH is used,
                the suffix ".tgz" is automatically appended to the pkg-name,
                whereas searching in the current directory uses pkg-name
                literally.

     PKG_TMPDIR, TMPDIR
                These are tried in turn (if set) as candidate directories in
                which to create a "staging area" for any files extracted by
                pkg_info from package files. If neither PKG_TMPDIR nor TMPDIR
                yields a suitable scratch directory, /var/tmp and /tmp are
                tried in turn.

                Since pkg_info requires very little information to be extract-
                ed from any package files examined, it is unlikely that these
                environment variables would ever need to be used to work
                around limited available space in the default locations.

TECHNICAL DETAILS

     Package info is either extracted from package files named on the command
     line, or from already installed package information in /var/db/pkg/<pkg-
     name>.
