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 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. 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 the package identified by pkg-name is currently installed, return code is 0, otherwise 1. The names of any pack- age(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 Set pkg_dbdir as the package database directory. If this option isn't specified, then the package database directory is taken from the value of the environment variable PKG_DBDIR if it's set, otherwise it defaults to /var/db/pkg. -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 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 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 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 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 Show the requirements script (if any) for each package. -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 /var/db/pkg/<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 transla- tion 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 {,} alter- nates have been implemented. Package version numbers can also be matched in a relational manner using the >=, <=, >, and < operators. For exam- ple, 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 ver- sions 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 counterparts, 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.
ENVIRONMENT
PKG_DBDIR If the -K flag isn't given, then PKG_DBDIR is the location of the package database directory. The default package database directory is /var/db/pkg. PKG_PATH This can be used to specify a semicolon-separated list of paths and URLs to search for package files. 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, /tmp, and /usr/tmp are tried in turn. Note that /usr/tmp may be cre- ated, if it doesn't already exist. Since pkg_info requires very little information to be extracted 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.
