Linux is an open source operating system developed by Linus Torvalds. It is developed and maintained by community on the internet. It has various distributions like Ubuntu, Fedora, CentOS, Oracle, Debian and many others. It is majorly used in cybersecurity. Strictly speaking, Linux refers only to kernel. To attain the full functionality of operating system, it is generally combined with GNU Utilities.

It consists of various commands for networking, file handling, file management and configuration. The commands for file handling are touch, cat, sort, grep, etc. The commands for networking are tty, stty, ftp, ssh and ping.

The commands for configuration can only be executed by the root user and sudo user. The sudo user is also known as SuperDo User. The sudo user is a regular user whose privileges are lifted and temporarily given the powers of root user.

The root user has the power to create, delete and manipulate its own account as well as other's account. They can change the system's configuration setting like date, time and other important tasks. The root user has access to all files and directories i.e. folders.

There are various objects like files and directories. Each object has permissions which determine what processes can be carried out by the user. There are three file permissions: read, write and execute which are denoted by r, w and x respectively.
