Pk/upk grew out of inconvenience of working with existing zoo of archivers that have widely varying cmdline interfaces and different conventions.

Pk/upk provide a simple common interface to all .tar*, .zip, .7z, winmail.dat, .deb, .rpm, .apk, etc.

To put all text files to my.tar.gz (under folder my/):

$ pk my.tar.gz *.txt

To put directory dir into dir.tgz just do

$ pk dir.tgz

To extract files from my.tar.gz to folder my/ (optionally creating it if it's missing in .tar.gz):

$ upk my.tar.gz
$ ls my/

TODO:

• support more popular formats (e.g. from http://en.wikipedia.org/wiki/List_of_archive_formats)
• options (e.g. override destination dir, force unnesting, -h, options for archiver, etc.)
• support .gz files (?)
• shell autocompletions
