Motivation

I'm writing this article because I want to stop relying on Google every time I come across a tar.gz file. After realizing that it would be more efficient to categorize and comprehend the available options, I decided to compile a list to make it easier to remember. The tar --help command produces an extensive list of options, and we have taken the liberty of extracting and organizing the most frequently used ones for your convenience.

tar option classification

x extract decompression case

Compression options

option keyword description
z gzip use gzip program like tar.gz
j bzip uses bzip2 program like tar.bz2

Device selection and switching
