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 extracts one or more files given as arguments on the command line.
Additionally, it may pass some options to the backend tools (like tar
options) when they are appended after ‘--´.
There is also a special option (-u) which is very useful for extracting
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.
Unlike gunzip, which decompresses the file in the target directory of
the source file, unp uses the current directory for output.
