sh(1) -c 'sleep 3 && echo I just woke up' & jobs(1posix)
command interpreter (shell)
-c               Read commands from the command_string operand instead of from the standard input.
                 Special parameter 0 will be set from the command_name operand and the positional
                 parameters ($1, $2, etc.)  set from the remaining argument operands.
If a command is terminated by the control operator &, the shell executes the command in the background in
a subshell.  The shell does not wait for the command to finish, and the return  status  is  0.
