PKG_CREATE(1) BSD General Commands Manual PKG_CREATE(1) NAME pkg_create -- a utility for creating software package distributions SYNOPSIS pkg_create [-YNOhjvyz] [-C conflicts] [-P pkgs] [-p prefix] [-f contents] [-i iscript] [-I piscript] [-k dscript] [-K pdscript] [-r rscript] [-s srcdir] [-t template] [-X excludefile] [-D displayfile] [-m mtreefile] [-o originpath] -c comment -d description -f packlist pkg-filename pkg_create [-YNhvy] -b pkg-name [pkg-filename] DESCRIPTION The pkg_create command is used to create packages that will subsequently be fed to one of the package extraction/info utilities. The input de- scription 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. OPTIONS The following command line options are supported: -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 represents. -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 a custom hack for the FreeBSD Ports Collection and is used to do `fake pkg_add' op- erations when a port is installed. In such cases, it is neces- sary 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 pre-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. It will be passed the package's name as the first argument. Note: if the -I option is not given, this script will serve as both the pre-install and the post-install script for the package, differentiating between the functionality by passing the keywords PRE-INSTALL and POST-INSTALL respectively, after the package's name. -I piscript Set piscript to be the post-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. It will be passed the package's name as the first argument. -C conflicts Set the initial package conflict list to conflicts. This is as- sumed to be a whitespace separated list of package names and is meant as a convenient shorthand for specifying multiple @conflicts directives in the packing list (see PACKING LIST DE- TAILS section below). -P pkgs Set the initial package dependency list to pkgs. 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 be- low). Each argument from the pkgs list could be in the form pkgname[:pkgorigin], where optional pkgorigin element denotes origin of each dependency from the list and it is recorded into the packing list along with the pkgname using @comment directive. -p prefix Set prefix as the initial directory "base" to start from in se- lecting files 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-in- stalled. It will be passed the package's name as the first argu- ment. Note: if the -K option is not given, this script will serve as both the de-install and the post-deinstall script for the pack- age, differentiating between the functionality by passing the keywords DEINSTALL and POST-DEINSTALL respectively, along with the package's name. -K pdscript Set pdscript to be the post-deinstall procedure for the package. This can be any executable program (or shell script). It will be invoked automatically when the package is later de-installed. It will be passed the package's name as the first argument. -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 de- termine whether or not installation/deinstallation should pro- ceed. To differentiate between installation and deinstallation, the keywords INSTALL and DEINSTALL are passed respectively, along with the package's name. -s srcdir srcdir will override the value of @cwd during package creation. -t template Use template as the input to mktemp(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 mktemp(3) to fill in with a unique ID. -X excludefile Pass excludefile as a -exclude-from argument to tar when creating final package. See tar man page (or run tar with --help flag) for further information on using this flag. -D displayfile Display the file (by concatenating it to stdout) after installing the package. Useful for things like legal notices on almost-free software, etc. -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. -o originpath Record an originpath, as location of the port from which package has been created in the FreeBSD Ports Collection. It should be in the form MASTERCATEGORY/PORTDIR. -j Use bzip2(1) utility to compress package tarball instead of gzip(1). Please note that this option is a NO-OP if the format of the resulting archive is explicitly specified by the recogniz- able suffix of pkg-filename. Currently pkg_create recognizes the following suffixes: .tbz, .tgz and .tar. -y Compatibility synonym for -j. -z Use gzip(1) utility to compress package tarball. -b pkg-name Create package file from a locally installed package named pkg-name. If the pkg-filename is not specified, then resulting archive will be created in the current directory and named pkg-name with an appropriate extraction suffix applied. PACKING LIST DETAILS The "packing list" format (see -f) is fairly simple, being nothing more than a single column of filenames to include in the package. However, since absolute pathnames are generally a bad idea for a package that could be installed potentially anywhere, there is another method of spec- ifying where things are supposed to go and, optionally, what ownership and mode information they should be installed with. This is done by em- bedding specialized command sequences in the packing list. Briefly de- scribed, these sequences are: @cwd directory Set the internal directory pointer to point to directory. All subsequent filenames will be assumed relative to this directory. Note: @cd is also an alias for this command. @srcdir 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. @exec command Execute command as part of the unpacking process. If command contains 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 Expand to the current directory prefix, as set with @cwd, in the example case /usr/local. %B Expand to the "basename" of the fully qualified filename, that is the current directory prefix, plus the last file- spec, minus the trailing filename. In the example case, that would be /usr/local/bin. %f Expand to the filename part of the fully qualified name, or the converse of %B, being 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 (extrac- tion) permissions. @option option Set internal package options, the only two currently supported ones being extract-in-place, which tells the pkg_add command not to extract the package's tarball into a staging area but rather directly into the target hierarchy (this is typically meant to be used only by distributions or other special package types), and preserve, which tells pkg_add to move any existing files out of the way, preserving the previous contents (which are also resur- rected on pkg_delete, so caveat emptor). @owner user Set default ownership for all subsequently extracted files to user. Use without an arg to set back to default (extraction) ownership. @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 docu- ment some particularly hairy sequence that may trip someone up later. @ignore Used internally to tell extraction to ignore the next file (don't copy it anywhere), as it's used for some special purpose. @ignore_inst Similar to @ignore, but the ignoring of the next file is delayed one evaluation cycle. This makes it possible to use this direc- tive in the packinglist file, so you can pack a specialized datafile in with a distribution for your install script (or some- thing) yet have the installer ignore it. @name name Set the name of the package. This is mandatory and is usually put at the top. This name is potentially different from the name of the file it came in, and is used when keeping track of the package for later deinstallation. Note that pkg_create will de- rive 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 ex- plicit directory cleanup method. This directive should appear at the end of the package list. If more than one @dirrm directives are used, the directories are removed in the order specified. The name directory will not be removed unless it is empty. @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 above). @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. @conflicts pkgcflname Declare a conflict with the pkgcflname package, as the two pack- ages contain references to the same files, and so cannot co-exist on the same system. ENVIRONMENT The environment variable PKG_TMPDIR names the directory where pkg_create will attempt to create its temporary files. If PKG_TMPDIR is not set, the directory named by the contents of TMPDIR will be used. If neither of PKG_TMPDIR and TMPDIR are set, the builtin defaults are used. FILES /var/tmp Temporary directory if environmental variables PKG_TMPDIR and TMPDIR are not set. /tmp The next choice if /var/tmp does not exist. /usr/tmp The last choice if /tmp is unsuitable.

AUTHORS Jordan Hubbard CONTRIBUTORS John Kohl <jtk@rational.com> BUGS Hard links between files in a distribution must be bracketed by @cwd di- rectives 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.
