>Usage
bzip2 is a command-line utility for compressing files using the Burrows-Wheeler
Block Sorting compression algorithm, which provides better compression rates than gzip.
>Synopsis
>Options
-z
compress: this option will simply compress the specified file in bzip2 format, saving it by default with .bz2 suffix
Example 1:
-zsh
bzip2 -z file1.txt
the file file1.txt will be compressed into a .bz2 format
-k
keep original: this option will create a compressed .bz2 version of the file without modifying the original one
Example 2:
-zsh
bzip2 -k file1.txt
this creates a compressed version of file1.txt without modifying the original
-d
decompress: this option is used to decompress .bz2 file, after decompression the .bz2 will no longer exists.
Example 3:
-zsh
bzip2 -d file.txt.bz2
this command decompress file.txt.bz2
-v
verbose: this option will display additional information about the compression or decompression process. This includes showing the name of each file being processed and information about the compression ratio.
Example 4:
-zsh
bzip2 -v file1.txt
This command compresses file1.txt into file1.txt.bz2 and displays information about the file
-f
bzip2 to overwrite existing files without asking for confirmation
-t
test integrity: This option is used to test the integrity of a compressed .bz2 file without decompressing it. If the file is valid it will generate no output.
Example 5:
-zsh
bzip2 -t file.txt.bz2
check the integrity of file.txt
