gzip command compresses single or multiple files. The compressed file ending with the extension (.gz), generally size of compressed file will be less than the size of the original file.

The gzip command uses a deflate algorithm, deflate algorithm a lossless data compression that creates smaller file sizes to make file transfer much faster.

gzip only reduces the size of a file and keeps the original file mode, ownership, and timestamp. It means compressed data remains the same after decompressing. To decompress the files, gunzip command is used and your original file will be back.

In this tutorial, you will learn about gzip command and uses of gzip command with examples

gzip -L def.txt.gz

gzip -d 123.txt.gz
