Compressing and Decompressing gz Files with Gzip

The gzip command (GNU zip) is specifically designed for compressing and decompressing "gz" files, typically identified by the ".gz" file extension. The syntax for the gzip command is gzip [OPTIONS] FILES.

Here are some commonly used options:

-c: Write the compressed output to standard output.
-d: Decompress a file.
-k: Keep the original file.
-v: Display compression ratio and other information.
1~9:Specify compression levels (higher numbers indicate higher compression ratios).

Example:

$ gzip * ←Compress all files in the current working directory
$ gzip -d *.gz ←Decompress all ".gz" files in the current working directory
$ gzip -9 *.cpp ←Compress all ".cpp" files with compression level 9
