How to silence gpg-agent?

[Jochen Saalfeld]

Hi Dahsamir,

I digged the code a bit and found, the piece of code. As you already assumed 
correctly, the trust-db is checked periodically, if 
the --no-auto-check-trustdb option is not set, and a log output is made, when 
the option --quiet is not set (./g10/trustdb.c:970), but the validate 
function is always called. So setting --quiet will just silence the 
otuput "gpg: checking the trustdb". If you dig a bit deeper in the validate 
function (./g10/trustdb.c:2057), you'll see that the logging output about the 
validation is always done and it doesn't care about any flag.

You can redirect the log output to a file with the --logger-fd option. You 
still have the output from the trustdb check, but maybe its easier to parse 
it from a file, then from the stdin.

Kind regards
Jochen
