This PR tries to fix #345 by using a TeeReader on the command stdout and stderr, and streaming the output to the log as it comes from the invoked command.

Following discution on my original PR #344, i have rewritten this PR to follow @moorereason 's advice (request to merge on development branch, remove unrelated commit)

hey @bdubertret any update on this PR from project leads? I am also interested in this feature as we have long running executables that we would like to see the log.

Don't call log.Fatal. Change these to something like:

log.Printf("[%s] error opening stdout: %s", rid, err)
return "", err

Sorry this has been sitting for so long. I like this PR and want to get it merged. However, there are merge conflicts now and a few changes I'd like to see made before we merge.

I'd be happy to rebase so we can get this live
