Hi guys,

I need to monitor Unix command execution inside the image. The commands use heavy computation so they usually report progress in the terminal.

Are OSProcess or OSSubprocess ready to do in-image monitoring so I can watch the same terminal output in the Transcript updating for example every 10 seconds?

Hi Hernan,

There is a tail -f example in OSSubprocess documentation that prints the result on an inpsector and updates it [1]. However, OSSubprocess has problems on Linux with the default VM... you must use the threaded heartbeat (not the itimer).. see recent threads discussions for this.��

Let me know if that works.

Particularly for OSProcess I couldn't find any method to fetch partial output.

Cheers,
