MSDOS command to check existance of command and exit batch if failed

<command> >NUL 2>&1 || ( echo <Command> not found. Please install <command> or check PATH variable! & pause & exit )
This is a command to be used inside of MS-DOS batch files to check existence of commands as preconditions before actual batch processing can be started. If the command is found, batch script continues execution. If not, a message is printed on screen, script then waits for user pressing a key and exits. An error message of the command itself is suppressed for clarity purpose.
Sample Output
bash --version >NUL 2>&1 || ( echo Bash not found. Please install cygwin or check PATH variable! & pause & exit )

Bash not found. Please install cygwin or check PATH variable!
Press any key to continue . . .

Hey RanyAlbeg, why do you rate me down, only because YOU are expecting UNIX only commands? FAQ doesn't restrict this website to UNIX only commands. There are also other non UNIX only commands, like sqlite or git commands.
