ec2-describe-snapshots -O xxxxxxxxxxxxxxx -W yyyyyyyyyyyyyy
Just gives me the 'usage', as if I'd written ec2-describe-snapshots -h with no other arguments.
This is on Ubuntu 12.04, java version:
java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.4) (6b24-1.11.4-1ubuntu0.12.04.1) OpenJDK Server VM (build 20.0-b12, mixed mode)
Seems like it's got to be something fairly simple, but even straceing it does not reveal anything in particular.
Tried running it as different users locally, with different credentials... nothing changes. If I omit the -O and -W it complains about needing the -K option, but nothing else changes its behaviour.
$ ec2-version 18.104.22.168 2011-11-01
