Printing command output

Chef Infra (archive)

Hi everyone,

Whats the easiest way to print command output while its running? I’ve found
older mailing list questions about this and things on SO but they mostly
point to setting chef logging to debug which is not what I want. I would
like to always print the output for this particular command as it often
takes awhile to run and has valuable information.

Setting the log level to info or debug is the only way currently: https://github.com/opscode/chef/blob/346aff0078a676d8c05319c017b891184426d004/lib/chef/provider/execute.rb#L55-L57

It wouldn’t be too difficult to write a patch to let you toggle that yourself, if you’re interested. It would also be pretty easy to write your own variant of the execute resource that always sets a live stream.

You could use ruby_block resources before and after the execute to set/reset the log level I think.

I sometimes use Tom Weiss’ technique from this thread so I’m not buried by debug output:

Something like this might work? :
gist:7fee6a550f11efafc48e · GitHub .

Last I recall there was a slight awkwardness because chef doesn't flush the
"io" object; I wrote this a while ago. It has been working well enough for
me :slight_smile:
