but the RUN botton can not display as an "STOP" icon, that's say I can not stop the running application by click the RUN button.

IIUC `gnome-terminal` is a front end for `gnome-terminal-server`. The server shows the terminal screens and `gnome-terminal` just tells it what to show and exits. Since Geany knows nothing about the server it watches the `gnome-terminal` process and when it exits it presumes the run is complete and switches the stop back to run. Unless you can find options that tell `gnome-terminal` not to behave like this there is not much Geany can do.

when I set as gnome-terminal -x "/bin/sh %c", it failure to lanuch

Thats a `gnome-terminal` problem, nothing to do with Geany, but I think it expects a list of arguments, not a single string. Also `-x` is deprecated.

[This](https://manpages.ubuntu.com/manpages/jammy/en/man1/gnome-terminal.1.html) was what google found for me, maybe a newer version has that option.

Works for me `gnome-terminal -e python3` returns immediately and a window with python REPL pops up, but `gnome-terminal --wait -e python3` does not return until after the Python REPL is exited.

Note `-e` is also deprecated, @eexpress use `--` and look at how the arguments need to be structured.

Ok so maybe `--wait`?

Thanks. --wait is works.
