Introduction

Welcome back to Day 22 of this practical Linux challenge! Today, we are diving into one of the most useful Linux commands: gzip.

When you think of compressing any file, think of gzip

What is the gzip Command?

gzip stands for GNU zip, a tool used to compress files, making them smaller and easier to store or transfer.

Core gzip Commands

More commonly used gzip command options are listed in the table below.

Worthy to note that this command works only for files, not folders.

Real-World Scenario: gzip Command

• Select a file you wish to compress. Compress using the gzip command. It ends with .gz

gzip demologs.txt

ls -lh   # to confirm it compressed

• Now you have seen how it works, let's decompress that .gz file back to the original format.

gunzip demologs.txt.gz 

• If you notice when we compressed, it did not keep the original file. Now, let's keep the original file and the compressed file.

gzip -k demologs.txt

ls -lh   # to confirm both the original and compressed file are there

Conclusion

Learning gzip might seem simple, but it is a crucial skill in Linux.

Mastering it helps you maintain lean storage and improve transfer speeds.
