Using tar together with gzip

Posted by – September 22, 2011

How can I extract a tar.gz or .tgz file?
Files with extension tar.gz or .tgz are tar files compressed with gzip. On Unix extract them with:

gunzip < file.tar.gz | tar xvf –
gunzip < file.tgz    | tar xvf –
Can gzip compress several files into a single archive?
Not directly. You can first create a tar file then compress it:

tar cvf –  filenames | gzip > file.tar.gz

UPX: the Ultimate Packer for eXecutables

Posted by – June 2, 2010

<UPX logo>

UPX is a free, portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers very fast decompression. Your executables suffer no memory overhead or other drawbacks for most of the formats supported, because of in-place decompression.

UPX is copyrighted software distributed under the terms of the GNU General Public License, with special exceptions granting the free usage for commercial programs as stated in the UPX License Agreement.

UPX uses the NRV compression library for compression services. A compatible but somewhat less efficient OpenSource implementation is available through the UCL compression library.

UPX aims to be Commercial Quality Freeware.

Ark: graphical archiving tool for KDE

Ark:

graphical archiving tool for KDE

Refers to:
http://packages.ubuntu.com/zh-cn/hardy/ark

Ark is a graphical program for managing various archive formats within the KDE environment. Archives can be viewed, extracted, created and modified from within Ark.

The program can handle various formats such as tar, gzip, bzip2, zip, rar and lha (if appropriate command-line programs are installed).

Ark can work closely with Konqueror in the KDE environment to handle archives, if you install the Konqueror Integration plugin available in the konq-plugins package.

This package is part of KDE, as a component of the KDE utilities module. See the ‘kde’ and ‘kdeutils’ packages for more information.
