shell, the standard command language interpreter

-c     Read commands from the command_string operand. Set the value of special parameter 0  (see  Special
       Parameters ) from the value of the command_name operand and the positional parameters ($1, $2, and
       so on) in sequence from the remaining argument operands.  No  commands  shall  be  read  from  the
       standard input.

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.
