The message command is useful for displaying specific information to the user. Running the command displays it on the status bar or, if the message cannot fit on the status bar, it will be displayed in a dialog box.

The message command is asynchronous. This means that when a message command is issued in a script, it does not wait for the user to click Dismiss before executing the rest of the script. The script continues execution regardless of the action of the user on this message.

The message command does not return any value or signal and is therefore not useful for dialog purposes.
