What is the output of the command 'echo $HOME' in Linux?

The command 'echo $HOME' outputs the home directory of the current user. In Linux, the environment variable $HOME contains the path to the user's home directory, which is where personal files and user-specific configurations are typically stored. When the command is executed, the echo command prints the value of this environment variable to the terminal.

This is particularly useful for users who may need to navigate to their home directory or reference it in scripts or commands. The home directory is typically structured as '/home/username' for regular users or '/root' for the root user in most Linux distributions.
