Hi,

[What do you mean by "gem event"?]

Ans 1: Check the gem help for all relevant options (like -q for quiet,
-s for silent, etc.) if you haven't already.

Ans2: (If Ans 1 doesn't help):

I haven't tried this out (not at my machine right now) but it may work,
if gem reads standard input for the answer:

Create a file called inp.txt that contains a "1" (withut the quotes)
followed by a newline.

gem gem_options your_gem_name < inp.txt

Another way, if you're on Linux or *NIX, may be:

yes | gem gem_options your_gem_name

The yes command writes (in an infinite loop), a "y" followed by a
newline, to standard output.
And if gem reads its standard input for the answer, this may work.

Best way is to try it out.
