Re: [Fab-user] return_code for run operation in fabric 0.9.2

[Jeff Forcier]

I guess you didn't read the tutorial? ;)

    http://docs.fabfile.org/0.9.2/tutorial.html#failure-handling

You just need to make use of the warn_only setting; it's typically
best paired with the "with settings():" context manager.

HTH,
