FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

pkg_info - a utility for displaying information on software packages

 

NAME

      pkg_info - a utility for displaying information on software packages
 

SYNOPSIS

      pkg_info [-bcdDEfgGiIjkKLmopPqQrRsvVxX] [-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      Show all currently installed packages.
 
      -b      Use the BLOCKSIZE environment variable for output even when the
              -q or -Q flag is present.
 
      -v      Turn on verbose output.
 
      -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).
 
      -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 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      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 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
              List all packages having the specified origin.
 
      -x      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      Like -x, but treats the pkg-name as an extended regular expres‐
              sion.
 
      -e 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
              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      Show revision number of package tools.
      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.
      pkg_add(1), pkg_create(1), pkg_delete(1), pkg_version(1), mktemp(3),
      mtree(8)

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
