zip commands

Zip is the most widely used archive file format that supports lossless data compression.

Facts about zip files:

A Zip file is a data container containing one or more compressed files or directories.
Compressed (zipped) files take up less disk space and can be transferred from one to another machine more quickly than uncompressed files.
Zip files can be easily extracted in Windows, macOS, and Linux using the utilities available for all operating systems.

$ zip index.zip index.html, index.php

If we want to add multiple files, directories, and subdirectories in the same archive:

$ zip -r index.zip index.html, index.php, index_directory
