You may also want to install some non-free packages like "unace-nonfree", "unrar-nonfree" and "lha" to extract archives of these types.
Install unp in ubuntu
sudo apt-get install unp
unpack all archives in a directory
unpack, for example, all .rar archives in a directory
unpack 1 archive
unpack several archives at the same time
unp archivefile1 archivefile 2
Some more examples
It doesn't extract files from RAR archives with full path
unp man page
unp – a shell frontend for uncompressing/unpacking tools
unp [-u] file [ files ... ] [ --- backend args ... ] ucat file [ files ... ]
unp is a small script with only one goal: Extract as many archives as possible, of any
kind and from any path to the current directory, preserving the subdirectory structure
where needed. Is a Do-What-I-Want utility and helps managing several extraction programs without looking for needed options for the particular tool or worrying about
the installation of the needed program.
Run unp without arguments to see the list of supported archive formats.
The special version ucat acts as wrapper for commands that can output the extracted
data to standard output, like bzip (bzcat), gzip (zcat), tar,zip and others.
unp extract one or more files given as arguments on the command line. Additionaly, it may pass some options to the backend tools (like taroptions) when they are appended after `–´.
There is also a special option (-u) which is very usefull for extracting of Debian packages. Using -u, unp extracts the package (i.e. the ar archive) first, then extracts data.tar.gz in the current directory and then control.tar.gz in control//.
unp will try to decompress into a FILE.unp if it get trouble with existing files. But don’t count on this feature, always look for free working space before using unp.
In contrary to gunzip which decompresses the file in the target directory of the source file,unp will use current directory for output.
