A command shell is a program that allows users to access the computer. It is ideally an interface that takes in commands and shows results. The shell is not an operating system, but rather it allows you to interact with the operating system via a terminal.
The following are a few Linux OS Basic Commands that you will commonly use:
pwd – This command is used to “Print Working Directory”. When you first open the Linux command, you are usually in the home directory of your user. This command shows you the entire path, starting at the root to the current location in the directory tree. Most commonly you will get a result of something like “/home/username/”.
ls – This command is used for directory listings and shows all directories present in the current file. List files in “long” format, one file per line. This also shows you additional info about the file, such as ownership, permissions, date, and size.

Conclusion – We learned a few things like basic Linux commands, such as how to print a working directory, how create a directory, input and output of data, how to copy, sort and delete files from your system, etc. I hope this has been helpful for you guys to understand the basic commands of a Linux Operating System.
