Question

I just need a Batch command that can check if some key was pressed, or a function that will return the keyboard key from the buffer.

Where can I find/download such a function?

Answer 1

read by default lets you wait until the user presses enter. It takes an optional parameter which is the name of a variable in which it’ll save the user input (everything up to the newline).

eivanec@sisifo ~ $ read test
hello
eivanec@sisifo ~ $ echo $test
hello

You can also specify a different character to wait for (instead of newline) with the -d switch.
