Question
Answer and Explanation
To clear all breakpoints in GDB (GNU Debugger), you can use the delete
command followed by a range or a wildcard. Here's how to do it:
1. Using the `delete` command with a range:
- If you know the breakpoint numbers, you can delete them by specifying a range. For example, if you have breakpoints numbered 1 through 5, you can delete them all with the command:
delete 1-5
- This command will remove breakpoints 1, 2, 3, 4, and 5.
2. Using the `delete` command with a wildcard:
- If you don't know the breakpoint numbers or want to delete all breakpoints regardless of their numbers, you can use the wildcard ``. The command is:
delete breakpoints
- This command will remove all breakpoints that are currently set.
3. Alternative using `delete` with no arguments:
- You can also use the `delete` command without any arguments. This will prompt GDB to ask if you want to delete all breakpoints. You can then confirm by typing 'y' or 'yes'.
delete
- GDB will then ask: "Delete all breakpoints? (y or n)"
- Type 'y' and press Enter to delete all breakpoints.
4. Verifying Breakpoint Deletion:
- After using any of the above methods, you can verify that all breakpoints have been cleared by using the info breakpoints
command. If no breakpoints are set, GDB will display a message indicating that there are no breakpoints.
info breakpoints
- If no breakpoints are set, GDB will output something like: "No breakpoints or watchpoints."
In summary, the most common and efficient way to clear all breakpoints in GDB is by using the command delete breakpoints
. This will remove all breakpoints regardless of their numbers.
