How does a command ends?

A command typically ends with a concluding action or statement that signifies its completion. This can be done through a specific punctuation mark, such as a period or exclamation point, or by issuing a follow-up instruction that indicates the task is finished. In programming, a command might end with a semicolon or newline character, depending on the language syntax. Ultimately, the end of a command indicates that the intended instruction has been fully expressed.
