.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
description of the input syntax is included in this document.
|
|
.Sh OPTIONS
|
|
The following command line options are supported.
|
|
.Bl -tag -width indent
|
|
.It Fl f Ar packinglist
|
|
Fetch ``packing list'' for package from the file
|
|
.Ar packinglist
|
|
or
|
|
.Cm stdin
|
|
if
|
|
.Ar packinglist
|
|
is a
|
|
.Cm -
|
|
(dash).
|
|
.Em "Mandatory."
|
|
.It Fl c Ar [-]desc
|
|
Fetch package ``one line description'' from file
|
|
.Ar desc
|
|
or, if preceded by
|
|
.Cm - ,
|
|
the argument itself. This string should also
|
|
give some idea of which version of the product (if any) the package
|
|
represents.
|
|
.Em "Mandatory."
|
|
.It Fl d Ar [-]desc
|
|
Fetch long description for package from file
|
|
.Ar desc
|
|
or, if preceded by
|
|
.Cm - ,
|
|
the argument itself.
|
|
.Em "Mandatory."
|
|
.It Fl Y
|
|
Assume a default answer of `Yes' for any questions asked.
|
|
.Em "Optional."
|
|
.It Fl N
|
|
Assume a default answer of `No' for any questions asked.
|
|
.It Fl O
|
|
Go into a `packing list Only' mode. This is a custom hack for the
|
|
.Em "FreeBSD 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.
|
|
.Em "Optional."
|
|
.It Fl v
|
|
Turns on verbose output.
|
|
.Em "Optional."
|
|
.It Fl h
|
|
Forces tar to follow symbolic links, so that the files they point to
|
|
are dumped, rather than the links themselves.
|
|
.It Fl i Ar iscript
|
|
Sets
|
|
.Ar 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.
|
|
.Em "Optional."
|
|
.It Fl P Ar pkgs
|
|
Sets the initial package dependency list to
|
|
.Ar pkgs.
|
|
This is assumed to be a whitespace separated list of package names
|
|
and is meant as a convenient shorthand for specifying multiple
|
|
.Cm @pkgdep
|
|
directives in the packing list (see PACKING LIST DETAILS section below).
|
|
.Em "Optional."
|
|
.It Fl p Ar prefix
|
|
Sets
|
|
.Ar prefix
|
|
as the initial directory ``base'' to start from in selecting files for
|
|
the package.
|
|
.Em "Optional."
|
|
.It Fl k Ar dscript
|
|
Sets
|
|
.Ar 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.
|
|
.Em "Optional."
|
|
.It Fl r Ar rscript
|
|
Sets
|
|
.Ar 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.
|
|
.Em "Optional."
|
|
.It Fl t Ar template
|
|
Use
|
|
.Ar template
|
|
as the input to
|
|
.Xr mktemp 3 .
|
|
By default, this is the string
|
|
.Pa /tmp/instmp.XXXXXX ,
|
|
but it may be necessary to override it in the situation where
|
|
space in your
|
|
.Pa /tmp
|
|
directory is limited. Be sure to leave some number of `X' characters
|
|
for
|
|
.Xr mktemp 3
|
|
to fill in with a unique ID.
|
|
.Em "Optional."
|
|
.It Fl X Ar excludefile
|
|
Pass
|
|
.Ar excludefile
|
|
as a
|
|
.Fl exclude-from
|
|
argument to
|
|
.Cm tar
|
|
when creating final package. See
|
|
.Cm tar
|
|
man page (or run
|
|
.Cm tar
|
|
with
|
|
.Fl -help
|
|
flag) for further information on using this flag.
|
|
.It Fl D Ar displayfile
|
|
Display the file (using
|
|
.Xr more 1 )
|
|
after installing the package. Useful for things like
|
|
legal notices on almost-free software, etc.
|
|
.It Fl m Ar mtreefile
|
|
Run
|
|
.Xr mtree 8
|
|
with input from mtreefile before the package is installed.
|
|
Mtree is invoked as
|
|
.Cm mtree
|
|
.Fl u
|
|
.Fl f
|
|
.Ar mtreefile
|
|
.Fl d
|
|
.Fl e
|
|
.Fl p
|
|
.Pa prefix ,
|
|
where
|
|
.Pa prefix
|
|
is the name of the first directory named by a
|
|
.Cm @cwd
|
|
directive.
|
|
.El

|
|
.Sh PACKING LIST DETAILS
|
|
The ``packing list'' format (see
|
|
.Fl 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 imbeding specialized command sequences
|
|
in the packing list. Briefly described, these sequences are:
|
|
.Bl -tag -width indent -compact
|
|
.It Cm @cwd Ar directory
|
|
Sets the internal directory pointer to point to
|
|
.Ar directory .
|
|
All subsequent filenames will be assumed relative to this directory.
|
|
Note:
|
|
.Cm @cd
|
|
is also an alias for this command.
|
|
.It Cm @srcdir Ar directory
|
|
Sets the internal directory pointer for _creation only_ to
|
|
.Ar directory .
|
|
That is to say that it overrides
|
|
.Cm @cwd
|
|
for package creation but not extraction.
|
|
.It Cm @exec Ar command
|
|
Execute
|
|
.Ar command
|
|
as part of the unpacking process. If
|
|
.Ar command
|
|
contains a any of the following sequences somewhere in it, they will
|
|
be expanded inline. For the following examples, assume that
|
|
.Cm @cwd
|
|
is set to
|
|
.Pa /usr/local
|
|
and the last extracted file was
|
|
.Pa bin/emacs .
|
|
.Bl -tag -width indent -compact
|
|
.It Cm "%F"
|
|
Expands to the last filename extracted (as specified), in the example case
|
|
.Pa bin/emacs
|
|
.It Cm "%D"
|
|
Expands to the current directory prefix, as set with
|
|
.Cm @cwd ,
|
|
in the example case
|
|
.Pa /usr/local .
|
|
.It Cm "%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 example case, that would be
|
|
.Pa /usr/local/bin .
|
|
.It Cm "%f"
|
|
Expands to the ``filename'' part of the fully qualified name, or
|
|
the converse of
|
|
.Cm %B ,
|
|
being in the example case,
|
|
.Pa emacs .
|
|
.El
|
|
.It Cm @unexec Ar command
|
|
Execute
|
|
.Ar command
|
|
as part of the deinstallation process. Expansion of special
|
|
.Cm %
|
|
sequences is the same as for
|
|
.Cm @exec .
|
|
This command is not executed during the package add, as
|
|
.Cm @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
|
|
.Cm @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
|
|
.Fl p )
|
|
.It Cm @mode Ar mode
|
|
Sets default permission for all subsequently extracted files to
|
|
.Ar mode .
|
|
Format is the same as that used by the
|
|
.Cm 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)
|
|
permissions.
|
|
.It Cm @owner Ar user
|
|
Sets default ownership for all subsequently extracted files to
|
|
.Ar user .
|
|
Use without an arg to set back to default (extraction)
|
|
ownership.
|
|
.It Cm @group Ar group
|
|
Sets default group ownership for all subsequently extracted files to
|
|
.Ar group .
|
|
Use without an arg to set back to default (extraction)
|
|
group ownership.
|
|
.It Cm @comment Ar string
|
|
Imbed a comment in the packing list. Useful in
|
|
trying to document some particularly hairy sequence that
|
|
may trip someone up later.
|
|
.It Cm @ignore
|
|
Used internally to tell extraction to ignore the next file (don't
|
|
copy it anywhere), as it's used for some special purpose.
|
|
.It Cm @ignore_inst
|
|
Similar to
|
|
.Cm @ignore ,
|
|
but the ignoring of the next file is delayed one evaluation cycle. This
|
|
makes it possible to use this directive in the
|
|
.Ar 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.
|
|
.It Cm @name Ar name
|
|
Sets 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 package
|
|
for later deinstallation. Note that
|
|
.Nm
|
|
will derive this field from the package name and add it automatically
|
|
if none is given.
|
|
.It Cm @dirrm Ar name
|
|
Declare directory
|
|
.Pa 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
|
|
.Cm @dirrm
|
|
directives are used, the directories are removed in the order specified.
|
|
The
|
|
.Pa name
|
|
directory will not be removed unless it is empty.
|
|
.It Cm @mtree Ar name
|
|
Declare
|
|
.Pa name
|
|
as an
|
|
.Xr mtree 8
|
|
input file to be used at install time (see
|
|
.Fl m
|
|
above). Only the first
|
|
.Cm @mtree
|
|
directive is honored.
|
|
.It Cm @display Ar name
|
|
Declare
|
|
.Pa name
|
|
as the file to be displayed at install time (see
|
|
.Fl D
|
|
above).
|
|
.It Cm @pkgdep Ar pkgname
|
|
Declares a dependency on the
|
|
.Ar pkgname
|
|
package. The
|
|
.Ar pkgname
|
|
package must be installed before this package may be
|
|
installed, and this package must be deinstalled before the
|
|
.Ar pkgname
|
|
package is deinstalled. Multiple
|
|
.Cm @pkgdep
|
|
directives may be used if hte package depends on multiple other packages.

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