The “start” command in Linux can be used to run a command in the background. When a command is run in the background, it executes as a separate process in the system and does not block the terminal. To run a command in the background, you can add an ampersand symbol (&) at the end of the command line. The background process will continue to run even after the terminal session is closed.
For example, the following command will start a program “example.sh” in the background:
$ ./example.sh &
