• Tar: The first one we’ll talk about today is tar, with tar you can archive and unarchive directories.
• Gzip: Gzip is being used for similar reasons but instead, it works on files for compressing purposes, the use of it also fairly simple.
• whoami: It’s quite simple, prints the name of the user who ran the command.
• who: Unlike “whoami”, the who command prints all the currently logged-in users, for example below here I have 2 terminals opened with 2 users and I get both of them with the terminals they opened.
• Date: Sometimes when you connect to a remote server over ssh knowing the current system date can be so important to see that you can simply run that command and the system date is at your service.
