PKG_CREATE(1)                BSD Reference Manual                PKG_CREATE(1)


     pkg_create - create software package distributions


     pkg_create [-OZhv] [-P dpkgs] [-C cpkgs] [-e emulation] [-p prefix]
                [-i iscript] [-k dscript] [-r rscript] [-s fake-prefix]
                [-S fake-base] [-t template] [-X excludefile] [-D displayfile]
                [-m mtreefile] -c comment -d description -f packlist pkg-name


     The pkg_create command is used to create packages that will subsequently
     be fed to one of the package extraction/info utilities. The input
     description and command line arguments for the creation of a package are
     not really meant to be human-generated, though it is easy enough to do
     so. It is more expected that you will use a front-end tool for the job
     rather than muddling through it yourself. Nonetheless, a short descrip-
     tion of the input syntax is included in this document.

     The options are as follows:

     -f packinglist
             Fetch "packing list" for package from the file packinglist or
             stdin if packinglist is a dash "-".

     -c [-]desc
             Fetch package "one line description" from file desc or, if pre-
             ceded by "-", the argument itself. This string should also give
             some idea of which version of the product (if any) the package

     -d [-]desc
             Fetch long description for package from file desc or, if preceded
             by "-", the argument itself.

     -Y      Assume a default answer of "Yes" for any questions asked.

     -N      Assume a default answer of "No" for any questions asked.

     -O      Go into a "packing list only" mode. This is used to do "fake
             pkg_add" operations when a package is installed. In such cases,
             it is necessary to know what the final, adjusted packing list
             will look like.

     -v      Turn on verbose output.

     -h      Force tar to follow symbolic links, so that the files they point
             to are dumped, rather than the links themselves.

     -i iscript
             Set iscript to be the install procedure for the package. This can
             be any executable program (or shell script). It will be invoked
             automatically when the package is later installed.

     -P dpkgs
             Set the initial package dependency list to dpkgs. This is assumed
             to be a whitespace separated list of package names and is meant
             as a convenient shorthand for specifying multiple @pkgdep direc-
             tives in the packing list (see PACKING LIST DETAILS section

     -C cpkgs
             Set the initial package conflict list to cpkgs. This is assumed
             to be a whitespace separated list of package names and is meant
             as a convenient shorthand for specifying multiple @pkgcfl direc-
             tives in the packing list (see PACKING LIST DETAILS section

     -e emulation
             Set the initial list of required binary emulations to emulation.
             This should be a whitespace separated list of emulations and is
             meant as a shorthand to specifying one or more @emul directives
             in the packing list.

     -p prefix
             Set prefix as the initial directory "base" to start from in
             selecting files for the package, and to record as the base for
             installing the package.

     -s fake-prefix
             Set fake-prefix as the real initial directory to start from in
             selecting files for the package.

     -S fake-base
             Set fake-base as the prefix to prepend to any file to select for
             the package.

     -k dscript
             Set dscript to be the de-install procedure for the package. This
             can be any executable program (or shell script). It will be in-
             voked automatically when the package is later (if ever) de-

     -r rscript
             Set rscript to be the "requirements" procedure for the package.
             This can be any executable program (or shell script). It will be
             invoked automatically at installation/deinstallation time to
             determine whether or not installation/deinstallation should

     -t template
             Use template as the input to mkstemp(3). 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 mkstemp(3)
              to fill in with a unique ID.

     -X excludefile
             Pass excludefile as a --exclude-from argument to tar when creat-
             ing final package. See tar man page (or run tar with --help flag)
             for further information on using this flag.

     -D displayfile
             Display the file (using more(1)) after installing the package.
             Useful for things like legal notices on almost-free software,

     -m mtreefile
             Run mtree(8) with input from mtreefile before the package is in-
             stalled. mtree is invoked as mtree -u -f mtreefile -d -e -p
             prefix, where prefix is the name of the first directory named by
             a @cwd directive.

     -Z      Do not try to create SV4CPIO archives.


     The "packing list" format (see -f) is fairly simple, being nothing more
     than a single column of filenames to include in the package. Directories
     (with a trailing slash) can also be added. They are then created at in-
     stallation time and deleted in reverse order upon package deletion.

     However, since absolute pathnames are generally a bad idea for a package
     that could be installed potentially anywhere, there is another method of
     specifying where things are supposed to go and, optionally, what owner-
     ship and mode information they should be installed with. This is done by
     embedding specialized command sequences in the packing list. Briefly
     described, these sequences are:

     @cwd directory
             Set the internal directory pointer to point to directory. All
             subsequent filenames will be assumed relative to this directory.

     @src directory
             Set the internal directory pointer for creation only to
             directory. That is to say that it overrides @cwd for package
             creation but not extraction.

     @emul   Binary emulation (kernel personality) the software needs. Only
             necessary for binary-only software. If several binary emulations
             are needed, each of them needs to be in a separate @emul command.

     @arch, @endfake
             Ignored, only exist for the sake of compatibility.

     @ldcache value
             Specifies whether ldconfig will be called for the directories
             that contain libraries (@lib directives). value should be 0 on
             static architectures, 1 otherwise. Deprecated, use @option
             ldcache et al instead.

     @info filename
             Special version of the file entry for GNU info files. Automati-
             cally includes chapter files (filename-*) and runs
             install-info(1) as needed.

     @man filename
             Special version of the file entry for manpages. For now, no
             differences to a normal file entry.

     @shell filename
             Special version of the file entry for shell binaries. For now, no
             differences to a normal file entry.

     @lib filename
             Special version of the file entry for shared libraries. Automati-
             cally adds ldconfig calls at installation and deinstallation time
             if they are missing.

     @exec command
             Execute command as part of the unpacking process. If command con-
             tains any of the following sequences somewhere in it, they will
             be expanded inline. For the following examples, assume that @cwd
             is set to /usr/local and the last extracted file was bin/emacs.

             %F      Expands to the last filename extracted (as specified); in
                     the example case, bin/emacs.

             %D      Expands to the current directory prefix, as set with
                     @cwd; in the example case /usr/local.

             %B      Expands to the "basename" of the fully qualified
                     filename, that is the current directory prefix, plus the
                     last filespec, minus the trailing filename. In the exam-
                     ple case, that would be /usr/local/bin.

             %f      Expands to the "filename" part of the fully qualified
                     name, or the converse of %B; in the example case, emacs.

     @unexec command
             Execute command as part of the deinstallation process. Expansion
             of special % sequences is the same as for @exec. This command is
             not executed during the package add, as @exec is, but rather when
             the package is deleted. This is useful for deleting links and
             other ancillary files that were created as a result of adding the
             package, but not directly known to the package's table of con-
             tents (and hence not automatically removable). The advantage of
             using @unexec over a deinstallation script is that you can use
             the "special sequence expansion" to get at files regardless of
             where they've been potentially redirected (see -p).

     @mode mode
             Set default permission for all subsequently extracted files to
             mode. Format is the same as that used by the chmod command (well,
             considering that it's later handed off to it, that's no
             surprise). Use without an arg to set back to default (extraction)

     @owner user
             Set default ownership for all subsequently extracted files to
             user. Use without an arg to set back to default (extraction) own-

     @group group
             Set default group ownership for all subsequently extracted files
             to group. Use without an arg to set back to default (extraction)
             group ownership.

     @comment string
             Imbed a comment in the packing list. Useful in trying to document
             some particularly hairy sequence that may trip someone up later.

             Used internally to tell extraction to ignore the next file (don't
             copy it anywhere), as it's used for some special purpose.

     @name name
             Set the name of the package. This is mandatory and is usually put
             at the top. This name is potentially different than the name of
             the file it came in, and is used when keeping track of the pack-
             age for later deinstallation. Note that pkg_create will derive
             this field from the package name and add it automatically if none
             is given.

     @dirrm name
             Declare directory name to be deleted at deinstall time. By de-
             fault, directories created by a package installation are not
             deleted when the package is deinstalled; this provides an expli-
             cit directory cleanup method. This directive should appear at the
             end of the package list. If more than one @dirrm directive is
             used, the directories are removed in the order specified. The
             name directory will not be removed unless it is empty. If several
             packages reference the same directory, it will only be removed
             after the last of those packages has been removed.

     @extra file
             Declare extra file file to be deleted at deinstall time, if user
             sets -c option. Those files are extra configuration files that
             are normally not deleted. If file ends with a slash, it is a

     @extraunexec command
             Extra command to execute when removing extra files.

     @sample filename
             The preceding file entry is a sample configuration file. It is
             copied to filename at pkg_add(1) time if filename does not al-
             ready exist. If it exists and is different from the sample, a
             warning is printed. If filename ends with a slash, it specifies a
             directory to be created instead. At pkg_delete(1) time, the entry
             is treated like @extra, i.e. it is only deleted if the -c option
             is given to pkg_add.

     @mtree name
             Declare name as an mtree(8) input file to be used at install time
             (see -m above). Only the first @mtree directive is honored.

     @display name
             Declare name as the file to be displayed at install time (see -D

     @pkgdep pkgname
             Declare a dependency on the pkgname package. The pkgname package
             must be installed before this package may be installed, and this
             package must be deinstalled before the pkgname package is dein-
             stalled. Multiple @pkgdep directives may be used if the package
             depends on multiple other packages.

     @pkgcfl pkgcflname
             Declare a conflict to the pkgcflname package. The pkgcflname
             package must not be installed if pkgname package gets installed
             because they install the same files and thus conflict. pkgcflname
             may use fnmatch(3) wildcards, csh-style alternates or the opera-
             tors <, <=, >, and >=. As an example for the latter,
             subversion<1.4 and subversion-<1.4.0-0 are equivalent.

     @option name
             Effects vary depending on name.

                     By default, a package conflicts with other versions of
                     the same package. With this option, the older package
                     version will still be noticed, but the installation will
                     proceed anyway.

                     This is a base package, i.e. one that is so important
                     that removing it will almost certainly break the system
                     (for example the pkgtools package). Base packages can
                     only be removed using the -f option to pkg_delete(1).

             dylib   Enable support for Darwin-style shared libraries. Shared
                     library names (@lib) are automatically converted into
                     dylib names. The links are also automatically added.

             gnu-ld  Enable support for GNU-style shared libraries, needed for
                     example under Interix. Automatically adds the library
                     links to the packing list and execute ldconfig according-

                     Support for "OpenBSD-style" shared libraries. Automati-
                     cally execute ldconfig for the shared library directories
                     during install and uninstall.

             static  Don't support shared libraries. This is the default if
                     none of the other options are given.


     pkg_add(1), pkg_delete(1), pkg_info(1), sysconf(3)


     The pkg_create command first appeared in FreeBSD.

             most of the work
     John Kohl
             refined it for NetBSD
     Thorsten Glaser

     Benny Siegert
             Effort to make the MirBSD package tools compatible to the new
             perlish OpenBSD package tools by Marc Espie.


     Hard links between files in a distribution must be bracketed by @cwd
     directives in order to be preserved as hard links when the package is ex-
     tracted. They additionally must not end up being split between tar invo-
     cations due to exec argument-space limitations (this depends on the value
     returned by sysconf(_SC_ARG_MAX)).

     Sure to be others.


     Since MirBSD #8, a patched paxtar is necessary because pkg_create creates
     SysV4 CPIO archives with CRC by default, instead of POSIX ustar archives.
     Use the -Z parameter to prevent pkg_create from adding -S to tar(1).

     This version is mostly compatible with the new OpenBSD package tools.
     Some of the new keywords are unsupported and will result in an error mes-
     sage from pkg_create.

     Using pathnames which contain spaces is unsupported.
