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

NAME
     pkg_info — a utility for displaying information on software packages

SYNOPSIS
     pkg_info [-bcdDEfghGiIjkKLmopPqQrRsvVxX] [-e package] [-l prefix]
	      [-t template] -a | pkg-name ...
     pkg_info [-qQ] -W filename
     pkg_info [-qQ] -O origin
     pkg_info

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

OPTIONS
     The following command line options are supported:

     pkg-name ...
	     The named packages are described.	A package name may either be
	     the name of an installed package, the pathname to a package dis‐
	     tribution file or a URL to an FTP available package.  Package
	     version numbers can also be matched in a relational manner using
	     the >=, <=, > and < operators.  For example,

		   pkg_info 'portupgrade>=20030723'

	     will match versions 20030723 and later of the portupgrade pack‐
	     age.

     -a, --all
	     Show all currently installed packages.

     -b, --blocksize
	     Use the BLOCKSIZE environment variable for output even when the
	     -q or -Q flag is present.

     -h, --help
	     Print help message.

     -v, --verbose
	     Turn on verbose output.

     -p	     Show the installation prefix for each package.

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

     -Q	     Be “quiet” as above but print preface output with the package
	     name.

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

     -d	     Show the long description field for each package.

     -D	     Show the install-message file for each package.

     -f	     Show the packing list instructions for each package.

     -g	     Show files that do not match the recorded checksum.

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

     -I	     Show an index line for each package.  This option takes prece‐
	     dence over all other package formatting options.

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

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

     -K, --keep
	     Keep any downloaded package in PKGDIR if it is defined or in cur‐
	     rent directory by default.

     -r	     For each of the specified packages, show the list of packages on
	     which it depends.

     -R	     For each of the specified packages, show the list of installed
	     packages which require it.

     -m	     Show the mtree(8) file (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.

     -s	     Show the total size occupied by files installed within each pack‐
	     age.

     -o	     Show the “origin” path recorded on package generation.  This path
	     is the directory name in the FreeBSD Ports Collection of the
	     underlying port from which the package was generated.

     -G, --no-glob
	     Do not try to expand shell glob patterns in the pkg-name when
	     selecting packages to be displayed (by default pkg_info automati‐
	     cally expands shell glob patterns in the pkg-name).

     -W, --which filename
	     For the specified 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 directories specified in the
	     environment variable PATH are searched using which(1).

     -O, --origin origin
	     List all packages having the specified origin.

     -x, --regex
	     Treat the pkg-name as a regular expression and display informa‐
	     tion only for packages whose names match that regular expression.
	     Multiple regular expressions could be provided, in that case
	     pkg_info displays information about all packages that match at
	     least one regular expression from the list.

     -X, --extended
	     Like -x, but treats the pkg-name as an extended regular expres‐
	     sion.

     -e, --exists package
	     If the package identified by package 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.

     -E	     Show only matching package names.	This option takes precedence
	     over all other package formatting options.	 If any packages
	     match, return 0, otherwise return 1.

     -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 do not necessarily want the output intermingled in
	     such a way that they cannot organize it.  This lets you add a
	     special token to the start of each field.

     -t, --template template
	     Use template as the argument to mktemp(3) when creating a
	     “staging area”.  By default, this is the string
	     /tmp/instmp.XXXXXX, but it may be necessary to override it in the
	     situation where space in your /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 pack‐
		   age and one would have to have a very small /tmp indeed to
		   overflow it.

     -V	     Show revision number of the packing list format.

     -P, --version
	     Show revision number of package tools.

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⟩.

ENVIRONMENT
     BLOCKSIZE	 If the environment variable BLOCKSIZE is set the block counts
		 will be displayed in units of that size block.

     PKG_TMPDIR	 Points to the directory where pkg_info creates its temporary
		 files.	 If this variable is not set, TMPDIR is used.  If both
		 are unset, the builtin defaults are used.

     PKG_DBDIR	 Specifies an alternative location for the installed package
		 database.

     PKG_PATH	 Specifies an alternative package location, if a given package
		 cannot be found.

     PKGDIR	 Specifies an alternative location to save downloaded packages
		 to.

FILES
     /var/tmp	  Used if the environment variables PKG_TMPDIR and TMPDIR are
		  not set, or if the directories named have insufficient
		  space.
     /tmp	  The next choice if /var/tmp does not exist or has insuffi‐
		  cient space.
     /usr/tmp	  The last choice if /tmp is unsuitable.
     /var/db/pkg  Default location of the installed package database.
