Linux exit command

In Linux, the “exit” command is used to exit or close the current terminal session. It allows you to terminate the shell or the terminal emulator you are working in. Here’s how to use the “exit” command:

1. Open a Terminal:
   Launch a terminal emulator on your Linux system.
2. Type the “exit” command:
   Simply type “exit” and press Enter. For example:

   exit

3. Exit the Terminal Session:
   The “exit” command will close the current terminal session, terminating the shell or the terminal emulator. The terminal window will be closed, and you will return to the parent environment, such as the desktop or another terminal window.
4. Exiting with a Status Code:
   If you want to exit with a specific status code, you can provide it as an argument to the “exit” command. For example, to exit with a status code of 0 (indicating successful execution), run:

   exit 0

The status code can be any integer value, and it is typically used to communicate the result of a script or command execution to the parent process.

5. Exiting a Script or Subshell:
   Within a script or subshell, the “exit” command is used to exit the script or subshell and return to the parent shell. For example, if you have a script called “myscript.sh” and you want to exit it prematurely, you can use the “exit” command within the script:

   #!/bin/bash

   # Script content...

   exit

When the “exit” command is encountered, the script or subshell will terminate, and the control will return to the parent shell.

6. Exiting a Remote SSH Session:
   If you are connected to a remote Linux system using SSH, the “exit” command is used to close the SSH session and return to your local machine. Simply type “exit” and press Enter to end the remote session.

The “exit” command provides a straightforward way to close the current terminal session, terminate a script, or exit a subshell. It allows you to cleanly exit the shell environment and return to the parent environment or close the terminal window altogether.
