Ability to Suppress Output

[snowsquizy]

Is your feature request related to a problem? Please describe.
I want to run the utility without any output unless an error occurs

Describe the solution you'd like
Command line option to suppress output

Additional context
This utility is being called from within another program with logging enabled. This will quickly increase the size of the log without any benefit. The display of errors should still occur.

Hi! Thanks for taking your time to place this issue. It is both a simple and a good idea, and I will probably implement it soon.

Hi! I have just merged 5cdebb7 (contributed by @derenix) which I think includes the feature you were asking for (currently using the command-line argument --quiet, but there could be some minor changes before a final release). Please take a look and let us know if it works for you.
