pkgtrans-apkgeng(1)

translate package format

Package: APKGENG, added for amigaux.

This is apkg's own copy, /usr/apkg/bin/pkgtrans, off the search path; pkgtrans at the shell runs the original: see pkgtrans(1).

pkgtrans - translate package format

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

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

a file system format to a datastream

a datastream to a file system format

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 SPECIFIERS, below.
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(1M), and pkgchk(1M), 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(1M).
device alias
Devices that have been specified in /etc/device.tab 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 /etc/device.tab
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 /export/packages.

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:

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 device:

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:

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:

pkgtrans /tmp/pkg1.pkg ~/tmp pkg1

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

When SOURCE_DATE_EPOCH is set to a number of seconds, pkgtrans -s archives each package's members in C sort order and, once the datastream file is written, rewrites the header of every member: inode numbers from 1 in archive order (hard links keep one number), owner, group and device 0, the modification time that epoch, and a directory's link count 2 plus its subdirectories. Names, modes, sizes and contents are unchanged, and every field is written in upper-case hex, whichever case cpio wrote, so a roll on Amix is the same bytes as one on another host. A value that is not a number of seconds is an error.

pkginfo(1), pkgmk(1), pkgparam(1), pkgproto(1), installf(1M), pkgadd(1M), pkgask(1M), pkgrm(1M), removef(1M), pkginfo(5), pkgmap(5)

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.
