[Bug 1604936] Re: Please document command-line options with --help and when called incorrectly

[Launchpad Bug Tracker]

This bug was fixed in the package shim-signed - 1.19~14.04.1

---------------
shim-signed (1.19~14.04.1) trusty; urgency=medium

  * update-secureboot-policy:
    - Add a --help option, document other options. (LP: #1604936)
    - Rework prompting to display our Secure Boot warning and explanation
      text more prominently, rather than forcing graphical users to hit
      "Help" to see the full explanation for why we ask about disabling
      Secure Boot. (LP: #1595611)

Bug description:
  [Impact]
  update-secureboot-policy did not include any help text.

  [Test case]
  - verify 'sudo update-secureboot-policy' works as expected (prompts to disable Secure Boot if it's enabled)
  - verify 'sudo update-secureboot-policy --disable' works as expected (same as above)
  - verify 'sudo update-secureboot-policy --enable' re-enables Secure Boot after it has been disabled (ie. after a run with --disable and a reboot)
  - verify 'update-secureboot-policy --help' displays help text.

  [Regression Potential]
  None. The default behavior without a parameter remains to try to disable Secure Boot if it's not already disabled. --enable is documented behind a new parameter --help which displays usage information.

  ---

  Subject says it all.  Having to read the source to discover --enable
  was irksome.  There should probably also be an opposite explicit
  --disable.
