pkgtrans - translate package format


pkgtrans [-inos] device1 device2 [pkginst]...


The pkgtrans utility translates an installable package from one format to
another. It translates:

o a file system format to a datastream

o a datastream to a file system format

o one file system format to another file system format


The options and arguments for this command are:

Copies only the pkginfo(5) and pkgmap(5) files.

Creates a new instance of the package on the destination
device if any instance of this package already exists, up
to the number specified by the MAXINST variable in the
pkginfo(5) file.

Overwrites the same instance on the destination device.
Package instance will be overwritten if it already exists.

Indicates that the package should be written to device2 as
a datastream rather than as a file system. The default
behavior is to write a file system format on devices that
support both formats.


Indicates the source device. The package or packages on this
device will be translated and placed on device2. See DEVICE

Indicates the destination device. Translated packages will be
placed on this device. See DEVICE SPECIFIERS, below.

Specifies which package instance or instances on device1
should be translated. The token all may be used to indicate
all packages. pkginst.* can be used to indicate all instances
of a package. If no packages are defined, a prompt shows all
packages on the device and asks which to translate.

The asterisk character (*) is a special character to some
shells and may need to be escaped. In the C-Shell, the * must
be surrounded by single quotes (') or preceded by a backslash


Packaging tools, including pkgtrans, pkgadd(8), and pkgchk(8), have
options for specifying a package location by specifying the device on
which it resides. Listed below are the device types that a package can be
stored to and retrieved from. Note that source and destination devices
cannot be the same.

Packages can be stored to a character or block device by
specifying the device identifier as the device. Common
examples of this device type are /dev/rmt/0 for a
removable magnetic tape and /floppy/floppy0 for the first
floppy disk on the system. pkgtrans can also produce
regular file system files in a stream format, which is
suitable for storage on a character device, web server,
or as input to pkgadd(8).

device alias
Devices that have been specified in /etc/ are
eligible for being the recipient or source of a package.
Common examples of this type of device specification are
spool (the default package device location) and disk1.
These names correspond to devices specified in

Packages can be stored onto a directory by specifying an
absolute path to a file system directory. The package
contents reside in a directory within the specified
directory. The package directory name must be identical
to its PKG specification in the pkginfo(5) file. An
example device specification of this type is


Example 1: Translating All Packages on the Floppy Disk

The following example translates all packages on the floppy drive
/dev/diskette and places the translations on /tmp:

example% pkgtrans /dev/diskette /tmp all

Example 2: Translating Packages on /tmp

The following example translates packages pkg1 and pkg2 on /tmp and
places their translations (that is, a datastream) on the 9track1 output

example% pkgtrans /tmp 9track1 pkg1 pkg2

Example 3: Translating Packages on /tmp

The following example translates pkg1 and pkg2 on /tmp and places them on
the diskette in a datastream format:

example% pkgtrans -s /tmp /dev/diskette pkg1 pkg2

Example 4: Translating a Package Datastream

The following example translates a package datastream into a file system
format package:

example% pkgtrans /tmp/pkg1.pkg ~/tmp pkg1


The MAXINST variable is set in the pkginfo(5) file and declares the
maximum number of package instances.

Application Packaging Developer's Guide


By default, pkgtrans does not translate any instance of a package if any
instance of that package already exists on the destination device. Using
the -n option creates a new instance if an instance of this package
already exists. Using the -o option overwrites an instance of this
package if it already exists. Neither of these options are useful if the
destination device is a datastream.

Package commands are largefile(7)-aware. They handle files larger than 2
GB in the same way they handle smaller files. In their current
implementations, pkgadd(8), pkgtrans and other package commands can
process a datastream of up to 4 GB.
