Which character, added to the end of a command, runs that command in the background as a child process of the current shell?
Which character, added to the end of a command, runs that command in the background as a child process of the current shell?
The character '&' when added to the end of a command in most Unix-like operating systems runs that command in the background as a child process of the current shell. This allows users to continue executing other commands while the original command runs in the background.
Certainly, here's an explanation of the other characters listed: A. `!`: The exclamation mark `!` is often used in shell history commands to refer to previous commands. For example, `!n` refers to the command with job number `n`. It is not used to run a command in the background. B. `+`: The plus sign `+` is not commonly used to run commands in the background. It's typically used in job control to bring a background job to the foreground, but not to start a command in the background.
