There are several special keyboard sequences which are commonly
used in UNIX.
- To interrupt a program during its execution, use
^c
(hold down the < control> key on
your keyboard, and type the letter c). This will usually stop
its execution. Do not use ^z.
- The key sequence
^z is used to pause the execution
of a program. If you use this you must type fg to resume
its execution.
- The character sequence
^s (control-s) will freeze
the output to your screen. It is useful to stop information from
flowing off your screen and it has the same effect of the
hold screen key (F1) on a VT220 terminal. If an unknowing
person accidently types ^s, he will think that the
terminal is broken because nothing else he types will echo onto
the screen.
-
^q (control-q) should be used to resume the output
to the screen after typing a ^s.
