ouch stands for Obvious Unified Compression Helper, and works on Linux, Mac OS and Windows.

It is a CLI tool to compress and decompress files that aims on ease of usage.



Run ouch and pass compressed files as arguments.

# Decompress 'a.zip'
ouch decompress a.zip

# Also works with the short version
ouch d a.zip

# Decompress multiple files
ouch decompress a.zip b.tar.gz

You can redirect the decompression results to a folder with the -o/--output flag.

Use the compress subcommand.

Accepts multiple files and folders, the last argument shall be the output file.

# Compress four files into 'archive.zip'
ouch compress 1 2 3 4 archive.zip

# Also works with the short version

# Compress folder and video into 'videos.tar.gz'

# Compress one file using 4 compression formats
