Public bug reported:
utils.execute() outputs a command line log with new lines.
As a result, the first line sometimes contains no useful information and it is
difficult for line-oriented log analyzing system to parse/analyze this. Not a
small number of current log analyzers are line-oriented, e.g., grep, elastic
search and so on.
It would be nice if it is output in a single line.
