Q. I’ve download ed .tbz file. How do I open .tbz file under Linux / UNIX operating system using a shell prompt or GUI application?

A. This is a tarball. A .tar or .tbz or .tgz file is commonly referred to as a Tarball, which is usually compressed to save disk space. Use tar command to open .tbz file.

First, open a terminal or shell prompt.

Extracts all files from a compressed Tar file of the name test.tbz or test.tar.bz2(bzipped file).
$ tar -xjf test.tbz

To extract to a specific folder called /tmp/test, use:
$ tar -xjf test.tbz -C /tmp/test

To view extracted file, use:
$ cd /tmp/test
$ ls -l
