It is often necessary to eliminate a breakpoint, watchpoint, or catchpoint once it has done its job and you no longer want your program to stop there. This is called deleting the breakpoint. A breakpoint that has been deleted no longer exists; it is forgotten.
clear command you can delete breakpoints according to
where they are in your program. With the
delete command you can
delete individual breakpoints, watchpoints, or catchpoints by specifying
their breakpoint numbers.
It is not necessary to delete a breakpoint to proceed past it. GDB automatically ignores breakpoints on the first instruction to be executed when you continue execution without changing the execution address.
Delete any breakpoints at the next instruction to be executed in the selected stack frame (see Selecting a Frame). When the innermost frame is selected, this is a good way to delete a breakpoint where your program just stopped.
Delete any breakpoints set at the specified location. See Specify Location, for the various forms of location; the most useful ones are listed below:
Delete any breakpoints set at entry to the named function.
Delete any breakpoints set at or within the code of the specified linenum of the specified filename.
delete [breakpoints] [range…]
Delete the breakpoints, watchpoints, or catchpoints of the breakpoint
ranges specified as arguments. If no argument is specified, delete all
breakpoints (GDB asks confirmation, unless you have
confirm off). You can abbreviate this command as
