pkgdelta(8)
|
||||
=========
|
||||
|
||||
Name
|
||||
----
|
||||
pkgdelta - package delta generation utility
|
||||
|
||||
|
||||
Synopsis
|
||||
--------
|
||||
'pkgdelta' [options] <package1> <package2>
|
||||
|
||||
|
||||
Description
|
||||
-----------
|
||||
'pkgdelta' is used to create package delta files between two versions of the
|
||||
same package. These files are essentially binary patches. linkman:pacman[8] can
|
||||
download deltas instead of full package upgrades, and use them with the
|
||||
previous versions of packages (in the package cache) to synthesize the upgraded
|
||||
version of the packages. This likely reduces download sizes for upgrades
|
||||
significantly.
|
||||
|
||||
'pkgdelta' requires linkman:xdelta3[1] to do its job.
|
||||
|
||||
|
||||
Options
|
||||
-------
|
||||
*--max-delta-size <ratio>*::
|
||||
Only create delta files if the delta is smaller than ratio * package_size.
|
||||
Possible values: 0.0 to 2.0.
|
||||
Recommended values: 0.2 to 0.9.
|
||||
Default value: 0.7
|
||||
|
||||
*--min-pkg-size <size>*::
|
||||
Minimal size of the package file in bytes to be considered for delta creation.
|
||||
Default value: 1048576 bytes = 1 MiB. This may be any absolute size in bytes or
|
||||
a human-readable value such as `4MiB` or `3.5MB`.
|
||||
|
||||
*-q, \--quiet*::
|
||||
Be quiet. Do not output anything but warnings and errors.
|
||||
|
||||
|
||||
Examples
|
||||
--------
|
||||
|
||||
$ pkgdelta libreoffice-3.3.2-1-x86_64.pkg.tar.xz libreoffice-3.3.2-2-x86_64.pkg.tar.xz
