unp is a small perl script which makes extraction of any archive files a bit easier. It support several compressors and archiver programs, chooses the right one(s) automatically and extracts one or more files in one go.

You may also want to install some non-free packages like “unace” (not in Debian)
and “lha” to extract archives of these types.

unp installation in debian

#apt-get install unp

that’s it installation completed now.If you want to use unp follow the below examples

Examples how to use unp

unp *.tar.gz
unp *.tar.bz
unp *.rpm
unp *.deb
unp *.zip
unp *.rar

For more details check man page below

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.

Ubuntu users can follow the same procedure.
