uz

Uz is a small tools to unpack files.

$ uz -v sample.tar.xz
sample_data/
sample_data/bar

It does not infer file-types from file endings but analyzes headers instead:

$ mv sample.tar.xz nothing-in-the-filename
$ uz -l nothing-in-the-filename
sample_data/
sample_data/bar

It also does the right thing in weird cases:

$ uz -A sample.tar.xz.bz2.gz.xz.gz.bz2
sample.tar.xz.bz2.gz.xz.gz.bz2: BZip <- gzip <- xz <- gzip <- BZip <- xz <- tarfile
cmd: bunzip2 --stdout | gunzip --to-stdout | xz --decompress --stdout | gunzip --to-stdout | bunzip2 --stdout | tar --extract --xz
$ uz sample.tar.xz.bz2.gz.xz.gz.bz2
$ ls
sample_data  sample.tar.xz.bz2.gz.xz.gz.bz2

Supported fileformats

It's fairly easy to add another archive or compression format to uz; right now it supports .bz2, .gz, .xz and .7z, .rar, .tar, .zip, -- as well as all combinations of those.

More formats are added as soon as the author runs into a file he needs to extract or via pull request.
