detach command
Detaches GDB from a process
Syntax
detach
Remarks
After GDB detaches from a process, the process will keep on running with no debugger attached to it. You can then attach back to it using the attach command.
Note that you can detach command is valid in all of those cases:
- When you have attached to a process with the attach command
- When you have started a process using the run command
- When you have connected to a gdbserver using the target command
If you want to terminate the debugged process instead of detaching from it, use the kill command.
Examples
In the following example we attach GDB to a running Linux process, detach from it and attach again:
(gdb) attach 14199

Compatibility with VisualGDB
Do not execute the detach command manually under Visual Studio. Use the VisualGDB Project Properties dialog to configure VisualGDB to execute the detach command when you exit debugging with Shift-F5.
