Hello there, In this article, we'll take a look at some of the basic commands used in Linux-based systems.

Anatomy of a basic Linux prompt

• In lines 1 and 2, we see hardik@nitro5-fedora. Here hardik is the username of the logged-in user and nitro5-fedora is the name of the pc.
• In line 1, ~ indicates that we are in the home directory.
• In line 2, / indicates that we are at the root of the filesystem.
• The $ symbol indicates that you are interacting with the system as a regular user. If you have sudo privileges, the $ turns into a #.

NOTE: From here on now, I’ll be using zsh instead of bash. But don't go away just yet. The commands discussed here work just the same on bash as well. :P
