Get progress of exec command

[fdservices]

Put simply I would like to follow the progress of a background task.

The task would be run as: exec some_task &

While it is running I would like to check its progress: while {true} {test_progress}

So I was thinking: set pid [exec some_task &]

and follow the progress of $pid ... but really I'm stuck.

Can someone give me a clue on how to proceed?

Thanks

If anyone is interested I worked it out:

set pid [exec some_task &]
while {[catch {exec ps --no-headers -p $pid}] == 0} {do_something; update}

May not be the best way but it seems to work anyway
