PKG_INFO(1)						    BSD General Commands Manual 					       PKG_INFO(1)

NAME

     pkg_info -- a utility for displaying information on software packages

SYNOPSIS

     pkg_info [-BbcDdFfhIikLmNnpqRrSsVvX] [-e package] [-E package] [-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 (if -F is also given), or a URL to an ftp-available package.

     The following command-line options are supported:

     -a      Show information for all currently installed packages.  See also -u.

     -B      Show some of the important definitions used when building the binary package (the ``Build information'') for each package.  Addition-
	     ally, 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 construction 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 package.  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 package.  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 translate it to a package name using the package database.  This can be used to query
	     information on a per-file basis, e.g. in conjunction with the -e flag to find out which package a file belongs to.

     -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 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 installation of the package are not listed.

     -l str  Prefix each information category header (see -q) shown with str.  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 dependencies), if any.

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

     -p      Show the installation prefix for each package.

     -Q      Show the definition of variable from the build information for each package.  An empty string is returned if no such variable defini-
	     tion 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 dis-
	     played.  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>.

     A filename can be given instead of a (installed) package name to query information on the package this file belongs to.  This filename is
     then resolved to a package name using the package database.  For this translation to take place, the -F flag must be given.  The filename
     must be absolute, compare the output of pkg_info -aF.

PACKAGE WILDCARDS

     In the places where a package name/version is expected, e.g. for the -e switch, 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 {,} alternates have been implemented.  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.  Additionally, ranges can be defined by giving a lower bound with > or >= and 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 candidate.
     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-1.3rc3 will sort before name-1.3 and after name-1.2.9.  Similarly name-1.3alpha2 will sort before
     name-1.3beta1 and they both sort before name-1.3rc1.  In addition, 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 The magic string ``pl'' equates to a patch level and has the same value as
     a dot in the dewey-decimal ordering schemes, as does the underscore '_'.
