[Bug 1900344] Re: Error behavior in "print" command does not work well in a pipeline

[Michael Hudson-Doyle]

I haven't checked it will help in your situation, but parted has a
--script command line flag which is documented as "never prompts for
user intervention" -- are you using that?

Title:
  Error behavior in "print" command does not work well in a pipeline

Status in parted package in Ubuntu:
  New

Bug description:
  I've got a script that includes "parted <device> print" in a pipeline
  with other things processing the output.  This works fine usually, but
  I just saw the error

  Error: The backup GPT table is corrupt, but the primary appears OK, so
  that will be used.

  and processing appeared to freeze because the following "OK/Cancel"
  does not include a newline and the pipeline held it in a buffer so it
  never appeared on the console.  There would be no way to answer
  anyway.

  So consider this two or three feature requests:
  - Since the message says "that one will be used" make to program just do that (it's just a "print" after all.)
  - Provide an option to assume "yes" for such questions (or to assume cancel")
  - Provide a command to fix the broken table with data from the good one
