Working with terminal commands is a crucial skill for developers. System administrators and IT experts might also benefit from it. In this blog article, we'll go over the most important terminal commands you need to know, address some often asked questions regarding Linux, and go over some entertaining commands you can use.

What are Terminal Commands?

Text-based commands used to interact with your computer's operating system are known as terminal commands or command-line interface (CLI) commands. These commands can be used to manage files, launch programmes, and modify system settings. Developers and system administrators frequently utilise the terminal to do work more quickly than by utilising a graphical user interface (GUI).

Unix vs. Linux

Linux and UNIX are separate operating systems with diverse histories, although having certain similarities.

The UNIX operating system family was created by AT&T Bell Laboratories in the 1970s. Currently, a number of businesses maintain their own UNIX versions, including IBM's AIX and Oracle's Solaris.

Contrarily, Linus Torvalds developed the open-source operating system Linux in the early 1990s. It is frequently referred to as a "UNIX-like" operating system because UNIX served as its inspiration. Many Linux distributions, such as Ubuntu, CentOS, and Debian, are available and well-liked by a sizable community.
