How to know if the execution in terminal is finished?

I found that I can use ITerminalServiceOutputStreamMonitorListener to monitor the output from terminal, but how can I know the execution is finished?

I'm not sure - what context are you trying to do this in? Are you trying to track commands in a user interactive terminal, or are you launching your own process? For the former, I don't think there is a way. VSCode has made lots of steps forward in this area where individual commands are tracked. For the latter, you can track the process itself.

Yes I'm trying to track commands execution in a user interactive terminal. Launching a command in the terminal, collecting the output until the the execution is done.

I don't think that is implemented today in CDT. My understanding is that tooling can use escape sequences to identify where in the command execution it is. For example see https://iterm2.com/documentation-escape-codes.html - especially FTCS_COMMAND_FINISHED which is the command for when a program execution is complete. Does ITerminalServiceOutputStreamMonitorListener receive the escape codes, or are they removed by the time the listener receives them? GNOME started putting these new escape sequences by default in PS1 in the last couple of years, see https://gitlab.gnome.org/GNOME/vte/-/commit/4d4e4807e1205ea10bca821af30caa0ec70325db

VSCode has a rich integration that uses the above and a bunch of other things too - see https://code.visualstudio.com/docs/terminal/shell-integration - some of that may be useful to integrate similar functionality into TM Terminal.

Thank you for the above detailed information, I'll do some tests for those sequences.
