I terminated osmosis several times during the run by Ctrl+c, and now it cannot do enen simplest tasks, giving an error: "The following named pipes () and 1 default pipes have not been terminated with appropriate output sinks."

$ osmosis --rx file="my.xml"

I'm on OSX 10.8, rebooting or even

 brew uninstall osmosis
 brew install osmosis

don't help. How can I fix it?

The command you are using will yield this error message on any system. The --rx opens a pipe and puts data in it. Osmosis expects you to specify where this data should go, but you don't. Add --write-null to your command line (which means "discard the data") and it will stop complaining. Of course, to make Osmosis do something useful, you'll have to specify something else than --write-null...

Thanks, that's my fault. --wx file="NNN" fixes that.
