There’s only 2 levels. -w for lousy, no -w for relatively quiet.
From the script, set $VERBOSE (or $-w) to boolean value.

matz.

I assume then that scripts are usually in quiet mode by default, and this is
actually still too noisy for me. I want a way to turn off all output
temporarily and then turn it back on.

Thanks,
Carl

Okay, since I can’t change the warning level to where I need it to be, is
there a way of temporarily redirecting output to /dev/null or something?
I’m not sure how to do that from inside a ruby script.

Thanks,
Carl

How “still too noisy” for you?

Try:

olderr = $stderr.clone
$stderr.flush
$stderr.reopen(“/dev/null”, “w”)
…
…
$stderr.flush
$stderr.reopen(olderr)
$olderr.close

I believe “flush” should not be necessary but I needed it to make it work
(very quick test on Windows Ruby 1.6.7).
