[Linux] Bash logout Usage: Exit the current shell session

Overview

The logout command is used in Bash to terminate a login shell session. When executed, it logs the user out of the current shell, effectively closing the terminal or console session. This command is particularly useful when you want to safely exit from a remote session or a terminal window.

Usage

The basic syntax of the logout command is as follows:

logout [options]

Common Options

The logout command does not have many options, but here are a couple of common ones:

• --help: Displays help information about the command.
• --version: Shows the version of the shell being used.

Common Examples

Example 1: Basic Logout

To log out of the current shell session, simply type:

logout

Example 2: Logout from a Remote Session

If you are connected to a remote server via SSH, you can log out by entering:

logout

Example 3: Using Logout in a Script

In a script, you can use logout to end a session after completing tasks:

#!/bin/bash
# Perform some tasks
echo "Tasks completed. Logging out..."
logout

Tips

• Always ensure that you have saved your work before executing logout, as it will close your session immediately.
• If you are using a non-login shell, logout may not work as expected; consider using exit instead.
• For remote sessions, remember that logging out will terminate your connection, so make sure you are ready to disconnect.
