Re: [Fab-user] try: run except run ?

Hi Jorge,

First, note that you may want to try using
`fabric.contrib.files.contains` instead of manually calling
``run('grep text file')``. It's got a couple of niceties that should
make it relatively useful, though I'm sure it could be expanded upon.

How exactly is it preventing it from happening? If you mean the
failure handler is causing Fabric to abort, then what you want is to
do the following to change Fab's behavior from "abort always" to "only
warn me, and keep going"::

    with settings(warn_only=True):
        run('foo')

However, note that ``contrib.files.contains`` already does this internally --
i.e. it will always return True or False and will never cause Fabric to bail
out -- which is another big reason to use it IMHO :)

Thanks,
Jeff
