The
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
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
description 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 preceded 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 , -yes
Assume a default answer of `Yes' for any questions asked.
-N , -no
Assume a default answer of `No' for any questions asked.
-O , -plist-only
Go into a `packing list Only' mode.
This is a custom hack for the
Fx Ports Collection
and is used to do `fake pkg_add' operations when a port is installed.
In such cases, it is necessary to know what the final, adjusted packing
list will look like.
-v , -verbose
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 assumed 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 DETAILS 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
directives in the packing list (see
Sx PACKING LIST DETAILS
section below).
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 prefix
Set
prefix
as the initial directory
``base''
to start from in selecting 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 invoked automatically when the
package is later (if ever) de-installed.
It will be passed the package's
name as the first argument.
Note
if the
-K
option is not given, this script will serve as both the de-install and the
post-deinstall script for the package, 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 determine whether or not
installation/deinstallation should proceed.
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.
-S basedir
basedir
will be prefixed to all
@cwd
during package creation.
-t , -template 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 installed.
Mtree is invoked as
mtree
-u
-fmtreefile
-d
-e
-p
prefix
where
prefix
is the name of the first directory named by a
@cwd
directive.
-o , -origin originpath
Record an
originpath
as location of the port from which package has been created in the
Fx 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 recognizable suffix of
pkg-filename
Currently
recognizes the following suffixes:
.tbz , .tgz
and
.tar
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.
-R , -recursive
When creating package file from a locally installed package
also create package files for all packages required by
pkg-name
Resulting archive(s) will be created in the current directory
and named using name of the respective package with appropriate
extraction suffix applied.
-x , -regex
Use basic regular expressions for
pkg-name
-E , -extended
Use extended (modern) regular expressions for
pkg-name
-G , -no-glob
Use exact matching for
pkg-name
-n
Run in
``no clobber''
mode.
If a package tarball exists, the
utility will not overwrite it.
This is useful, for example, when multiple packages are saved with
several consecutive runs of
with the
-Rb options.
Saving common dependencies multiple times would do a lot of duplicate
work in this case.
The
-n
option avoids repackaging common dependencies multiple times.
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 specifying where things are supposed to go
and, optionally, what ownership 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.
If no
directory
argument is given, it will set the internal directory pointer to the
first prefix value.
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 filespec, 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 contents (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 have
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 is later handed off to it, that is
no surprise).
Use without an arg to set back to default (extraction)
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 resurrected 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 document some particularly hairy sequence that
may trip someone up later.
@noinst option file
Specify that the package would have installed
file
if
option
had been specified at build time.
The action of
@noinst
is the same that
@comment
(which is doing nothing, it is just additional information).
@ignore
Used internally to tell extraction to ignore the next file (do not
copy it anywhere), as it is 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 directive in the
packinglist
file, so you can pack a
specialized datafile in with a distribution for your install script (or
something) 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
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 default, directories created by a
package installation are not deleted when the package is deinstalled;
this provides an explicit 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 deinstalled.
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 packages 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
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.
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
extracted.
They additionally must not end up being split between
tar
invocations due to exec argument-space limitations (this depends on the
value returned by
sysconf (_SC_ARG_MAX ) .);
