The bzip2(1) tool uses the Burrows-Wheeler algorithm to compress or decompress files. When invoked with the bzip2 command, it will default to compression. It can also be invoked as bunzip2, defaulting to decompression.

Contents

Compressing

To compress a file, you can run:

$ bzip2 test.txt

This will replace test.txt with a compressed version of the file, called test.txt.bz2.

Decompressing

To decompress, run:

$ bunzip2 test.txt.bz2

The compressed version will then be replaced with the original test.txt.

The -d option to bzip2 has the sam effect as running bunzip2.

$ bzip2 -d test.txt.bz2

Writing to stdout

The bzip2 program can also be invoked as bzcat, in which case it will print the decompressed file on stdout.

$ bzcat test.txt.bz2
This is the content of test.txt
