How Do I Remove A Single Breakpoint With GDB?

To remove a single breakpoint in GDB (GNU Debugger), you can use the delete command followed by the breakpoint number.

Steps to Remove a Single Breakpoint:

  1. List Breakpoints: First, you need to know the breakpoint number. You can list all active breakpoints with the info breakpoints command.
    (gdb) info breakpoints
    

    This will display something like:

    Num     Type           Disp Enb Address            What
    1       breakpoint     keep y   0x0804846a in main at program.c:10
    2       breakpoint     keep y   0x08048477 in main at program.c:20
    

    In this case, the breakpoints have numbers 1 and 2.

  2. Delete a Specific Breakpoint: To remove a breakpoint, use the delete command followed by the breakpoint number.

    For example, to remove breakpoint number 1:

    (gdb) delete 1
    
  3. Confirm Deletion: If you want to ensure the breakpoint is deleted, you can list the breakpoints again using info breakpoints to verify.
    (gdb) info breakpoints
    

Additional Notes:

  • Delete all breakpoints: If you want to delete all breakpoints, use the delete command without specifying a number:
    (gdb) delete
    
  • Delete multiple breakpoints: You can delete a range of breakpoints by specifying the range:
    (gdb) delete 1 2
    

This will remove breakpoints 1 and 2.

By following these steps, you can efficiently remove a single breakpoint or manage breakpoints within GDB.
