[GRASS-user] suppress output to terminal completely

[Hufkens Koen]

I use the --quiet option but then the output changes from

tracing patch 1
tracing patch 2

etc...

to tracing patch 1 and then only flipping this number and not rewriting the line.

So it does not respect the --quiet option completely...

And the 2> /dev/null option seems to work, now my script can run in the background and I can keep working.

Thanks,
Koen

GRASS modules send informative messages to stderr, not stdout - so adding
2>/dev/null
(Bash shell syntax) should work. But have you tried r.le.patch --quiet 
first of all? I'm not sure if r.le.patch respects the --quiet setting, but 
redirecting stderr to /dev/null definitely will work.
