unp Configuration in Debian

unpack (almost) everything with one command

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.

NAME
unp - a shell frontend for uncompressing/unpacking tools

SYNOPSIS
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.

USAGE
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/<filename>/.

NOTES
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.
