You can use the Run[] command:
Run[expr_1,expr_2,... ] generates the printed form of the expressions
expr_i, separated by spaces, and runs it as an external, operating
system, command.
Note that
!"command" is the same of
Run["command"]
As an example, under windows the input
!cmd
starts the MS-DOS console. In this case after the ms-dos console is
started the front end still looks like evaluating, because it's waiting
for the end of the external command. When you close the ms-dos console,
mathematica will know that the execution of the external, system code is
ended and you'll be able to do new computation in the front end.
If you evaluate
!cmd
1+1
you'll see..
