PKG_INFO(1)             NetBSD General Commands Manual             PKG_INFO(1)

NAME
     pkg_info -- a utility for displaying information on software packages

SYNOPSIS
     pkg_info [-BbcDdFfhIikLmNnpqRrSsVvX] [-E pkg-name] [-e pkg-name]
              [-K pkg_dbdir] [-l prefix] pkg-name ...
     pkg_info [-a | -u] [flags]
     pkg_info [-Q variable] pkg-name ...

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 (with our without
     version), a pattern matching several installed packages (see the PACKAGE
     WILDCARDS section for a description of possible patterns), the pathname
     to a binary package, a filename belonging to an installed package (with
     -F), or a URL to an FTP-available package.

     The following command line options are available:

     -a      Show information for all currently installed packages.  See also
             -u.  When neither -a nor -u is given, the former is assumed.

     -B      Show some of the important definitions used when building the
             binary package (the ``Build information'') for each package.
             Additionally, any installation information variables (lowercase)
             can be queried, too.  In particular, automatic tells if a package
             was installed automatically as a dependency of another package.

     -b      Show the NetBSD RCS Id strings from the files used in the con-
             struction of the binary package (the ``Build version'') for each
             package.  These files are the package Makefile, any patch files,
             any checksum files, and the packing list file.

     -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 existence of a given pack-
             age.  If a package identified by pkg-name is currently installed,
             return code is 0, otherwise 1.  The name of the best matching
             package found installed is printed to stdout unless turned off
             using the -q option.  pkg-name can contain wildcards (see the
             PACKAGE WILDCARDS section below).

     -e pkg-name
             This option allows you to test for the existence of a given pack-
             age.  If a package identified by pkg-name is currently installed,
             return code is 0, otherwise 1.  The names of any package(s) found
             installed are printed to stdout unless turned off using the -q
             option.  pkg-name can contain wildcards (see the PACKAGE
             WILDCARDS section below).

     -F      Interpret any pkg-name given as filename, and query information
             on the package that file belongs to.  This can be used to query
             information on a per-file basis.  See the TECHNICAL DETAILS sec-
             tion below for more information.

     -f      Show the packing list instructions for each package.

     -h      Print usage message and exit.

     -I      Show the index entry for each package.  This option is assumed
             when no arguments or relevant flags are specified.

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

     -K pkg_dbdir
             Override the value of the PKG_DBDIR configuration option with the
             value pkg_dbdir.

     -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.  Files that were created dynamically during installa-
             tion of the package are not listed.

     -l prefix
             Prefix each information category header (see -q) shown with
             prefix.  This is primarily of use to front-end programs that 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.

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

     -N      Show which packages each package was built with (exact dependen-
             cies), if any.

     -n      Show which packages each package needs (depends upon), if any.

     -p      Show the installation prefix for each package.

     -Q variable
             Show the definition of variable from the build information for
             each package.  An empty string is returned if no such variable
             definition is found for the package(s).

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

     -R      For each package, show the packages that require it.

     -r      For each package, show the packages that require it.  Continue
             recursively to show all dependents.

     -S      Show the size of this package and all the packages it requires,
             in bytes.

     -s      Show the size of this package in bytes.  The size is calculated
             by adding up the size of each file of the package.

     -u      Show information for all user-installed packages: automatically
             installed packages (as dependencies of other packages) are not
             displayed.  See also -a.

     -V      Print version number and exit.

     -v      Turn on verbose output.

     -X      Print summary information for each package.  The summary format
             is described in pkg_summary(5).  Its primary use is to contain
             all information about the contents of a (remote) binary package
             repository needed by package managing software.

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

     When the -F option is used, a filename can be given instead of a package
     name to query information on the (installed) package that file belongs
     to.  The filename is resolved to a package name using the package data-
     base.  The filename must be absolute, as in the output of
           pkg_info -aF.
     For example,
           pkg_info -eF /path/to/file
     can be used to display the package the given file belongs to, and
           pkg_info -LF /path/to/file
     can be used to display all files belonging to the package the given file
     belongs to.

PACKAGE WILDCARDS
     In the places where a package name/version is expected, e.g., for the -e
     option, several forms can be used.  Either use a package name with or
     without version, or specify a package wildcard that gets matched against
     all installed packages.

     Package wildcards use fnmatch(3).  In addition, csh(1) style {,} alter-
     nates have been implemented.  Package version numbers can also be matched
     in a relational manner using the ``>='', ``<='', ``>'', and ``<'' opera-
     tors.  For example,
           pkg_info -e 'name>=1.3'
     will match versions 1.3 and later of the ``name'' package.  (Make sure to
     use shell quoting.)  Additionally, ranges can be defined, by giving both
     a lower bound (with ``>'' or ``>='') as well as an upper bound (with
     ``<'' or ``<='').  The lower bound has to come first.  For example,
           pkg_info -e 'name>=1.3<2.0'
     will match versions 1.3 (inclusive) to 2.0 (exclusive) of package
     ``name''.

     The collating sequence of the various package version numbers is unusual,
     but strives to be consistent.  The magic string ``alpha'' equates to
     ``alpha version'', and sorts before a beta version.  The magic string
     ``beta'' equates to ``beta version'', and sorts before a release candi-
     date.  The magic string ``rc'' equates to ``release candidate'', and
     sorts before a release.  The magic string ``pre'', short for
     ``pre-release'', is a synonym for ``rc''.  For example,
     ``name-1.3alpha2'' will sort before ``name-1.3beta1'', and they both sort
     before ``name-1.3rc1''.  Similarly, ``name-1.3rc3'' will sort before
     ``name-1.3'', and after ``name-1.2.9''.  The magic string ``pl'' equates
     to ``patch level'', and has the same value as a dot (`.') in the dewey-
     decimal ordering schemes, as does the underscore (`_').  Additionally,
     alphabetic characters sort in the same place as their numeric counter-
     parts, so that ``name-1.2e'' has the same sorting value as
     ``name-1.2.5''.
