To remove all commands from a breakpoint, type commands and
follow it immediately with end; that is, give no commands.
With no bpnumber argument, commands refers to the last
breakpoint set.
You can use breakpoint commands to start your program up again.
Simply use the continue command, or step, or any other
command that resumes execution.
Specifying any command resuming execution (currently continue,
step, next, return, jump, quit and their abbreviations) terminates
the command list (as if that command was immediately followed by end).
This is because any time you resume execution

(even with a simple next or step), you may encounter
another breakpoint--which could have its own command list, leading to
ambiguities about which list to execute.
If you use the 'silent' command in the command list, the
usual message about stopping at a breakpoint is not printed. This may
be desirable for breakpoints that are to print a specific message and
then continue. If none of the other commands print anything, you
see no sign that the breakpoint was reached.
