pigz (Ubuntu)

Bug Description

Binary package hint: pigz

Ubuntu 9.10, i386

There is pigz program to compress files but I miss unpigz program to uncompress archives.

pigz should be replacement for zip and gzip
unpigz should be a replacement for unzip and gunzip

$ pigz -V
pigz 2.1.4

$ unpigz
unpigz: command not found

man unpigz
No manual entry for unpigz

$ apt-cache search unpigz

$ apt-cache search pigz
pigz - Parallel Implementation of GZip

Workaround is to use pigz with switch "d", to decompress archive...

Bug is marked as "wishlist". When you check official man page for pigz (http://www.zlib.net/pigz/pigz.pdf), you will see that command unpigz is described there. This official man page was the trigger to realize that unpigz command is missing in Ubuntu.

The distributed binary is all that is needed. If it is known as "unpigz", it will unpack the archive, otherwise it will create it.

A simple workaround is:
sudo ln -s /usr/bin/pigz /usr/local/bin/unpigz

However, I disagree that this is a "wishlist". Vital functionality is missing from the package.
