Instead of using tee, we redirect to a file and then use watch to display the file contents at regular intervals.

One example:

ecm > results.txt &
watch -n 60 cat results.txt

The & puts the ecm process into the background while leaving it running.

Or you could grep the results file for factor lines:

ecm > results.txt &
watch -n 60 grep actor results.txt

You will want to read up on "job control".
"tail -f" is how I do it.
