Linux compression and packaging method 3: bzip2, bzcat command

We have met many Linux compression and packaging methods. The following describes the concepts of bzip2 and bzcat commands in Linux compression and packaging methods. This article provides a variety of examples for you to view, I believe there will be a lot of gains after reading this ....

Bzip2, bzcat command
[Root @ linux ~] # Bzip2 [-cdz] File Name
[Root @ linux ~] # Bzcat file name .bz2

Parameters:
◆-C: output the data generated during the compression process to the screen!
◆-D: extracted Parameters
◆-Z: Compression Parameters
◆-#: Same as gzip, it is used to calculate the compression ratio.-9 is the best, and-1 is the fastest!

Example 1:
Compress/tmp/man. config with bzip2.
[Root @ linux tmp] # bzip2-z man. config
At this time, man. config will become man.config.bz2!

Example 2:
Read the file content in Example 1!
[Root @ linux tmp] # bzcat man.config.bz2
The man.config.bz2 extracted file content is displayed on the screen !!

Example 3:
Decompress the file in Example 1
[Root @ linux tmp] # bzip2-d man.config.bz2

Example 4:
Compress man. config in Example 3 with the optimal compression ratio and keep the original file
[Root @ linux tmp] # bzip2-9-c man. config> man.config.bz2
