unt stands for until and will continue execution up until a specified line. If no line number is specified, then it behaves similarly to the
n command, because execution will continue just one line.
The only difference is that this is not logically executed, and so the
unt command will iterate through entire loops automatically, instead of just moving forward one iteration. If you do supply a line number,
unt will act like the
c command, except you’re telling it where to stop.
