Questions tagged [background-process]
On POSIX systems a background-process is created in a shell by either adding an ampersand symbol after a command (e.g. ./script.sh &) or by pressing CTRL+Z while the command is being executed. The command will then run independently from the shell but will still write stdout and stderr output to the shell from where it has been started. It can only be stopped with the kill command.
