Re: [S3tools-general] s3cmd in perl - how do I suppress responses

[John B. <joh...@gm...>]

Andi and others:

With other command line tools, there is usually a "warnings only" 
switch, in which the output is suppressed when things are normal, but if 
a problem occurs, then it will respond with the problem.

For example, ffmpeg has the -loglevel switch, which can be set to 
'quiet' 'warning' 'verbose' etc. based on the amount of output you want 
returned, if any.

Yes, I can send the responses to null, but then I would never know if 
there was a problem.  I could look at the responses, and add a 
conditional for a warning alert, but I do not know all of the possible 
warning responses from s3cmd. Like I said, most command line tools 
already have a warnings only switch for this reason.

I guess I am going to give on on using s3cmd for now, since there does 
not seem to be a warnings only option, which is unfortunate, as I like 
many of the things it does over some of the other  s3 tools. Perhaps the 
author will add this option in the future.
