p7zip
p7zip is a command-line port of 7-Zip for POSIX compliant systems such as Unix, OS X, BeOS and Amiga. Created by Igor Pavlov, the 7-Zip compression type uses one of the highest compression ratios currently available. Since version 4.10 it supports little and big endian machines.[1]

- 7zr
If compiled with the wxwidgets USE flag it also provides a graphical interface.
- 7zG
- 7zFM
Also a wrapper included is for 7za:

Extraction to current directory
To extract all files from an archive to the current directory without using directory names, use the following command:
user $7za e <archive name>Where <archive name> is to be replaced with the archive's name.
To extract with full paths, use the following command:
user $7za x <archive name>Extraction to a new directory
To extract into a new directory, use the following command:
user $7za x -o<folder name> <archive name>Where <folder name> is the name of the new folder.
