How set input file in Jquery?

What is wrong with this batch file?

• When I try to open this batch file that I created, it just opens and closes straight away again. The batch file is big, but its simple nonetheless. @echo off cd c:\ color 02 cls echo Would you like to Shut Down, Restart, Log Off or abort a shutdown? [ S | R | L | A ] set /p input= if /i %letter% == shutdown goto shutdown if /i %letter% == s goto shutdown if /i %letter% == restart goto restart it /i %letter% == r goto restart if /i %letter% == logoff goto logoff if /i %letter% == l goto logoff if /i %letter% == abort goto abort if /i %letter% == a goto abort goto invalid exit :shutdown cls shutdown -s -t 15 -c "The system will shut down in 15 seconds." cls echo Would you like to abort shut down? [ Y | N ] set /p input= if /i %letter% == y goto abort if /i %letter% == n goto exit if /i %letter% == yes goto abort if /i %letter% == no goto exit goto invalid2 exit :restart cls echo Would you like to abort restart?

• Answer:

  You'll have to run this from a command prompt ( Start->Run->cmd ). Whats happening is that it's opening a command prompt, probably displaying an error an exiting again - closing the window.
