OPTIONS         top

 -c, --ctty Set the controlling terminal to the current one. -f, --fork Always create a new process. -w, --wait Wait for the execution of the program to end, and return the exit status of this program as the exit status of setsid. -h, --help Display help text and exit. -V, --version Display version and exit.
