Title:
  getopt example in docs incorrectly implies /bin/sh may not be used
  (PATCH)

Status in util-linux package in Ubuntu:
  Confirmed

Bug description:
  getopt(1) works with /bin/sh, bash, and probably other Bourne-ish
  shells (as well as csh-family shells with the appropriate option).

  However the included examples give the impression that something about
  getopt(1) makes it incompatible with /bin/sh, leading one to assume
  that scripts MUST use bash instead of sh.    The author probably meant
  merely that the "bash" example would not work with tcsh; however less-
  experienced script writers might not find that to be obvious.

  First of all, the Bourne-syntax example unnecessarily uses bash, i.e.
  leading one to wonder why the more-universal sh shell could not be
  used.   And there is a comment in the example saying "This program
  will only work with bash(1)".

  
  SUGGESTED IMPROVEMENT (patch attached):

  . Rename /usr/share/doc/util-linux/examples/getopt-parse.bash to
  getopt-parse.sh

  . Change the example to use /bin/sh instead of bash, and change the
  comment to say that that example works only with sh-compatible shells,
  including bash.


  P.S.  The --shell option to getopt(1) accepts arguments 'sh', 'bash',
  'csh', and 'tcsh', however internally there is no difference between
  'sh' and 'bash' (or between 'csh' and 'tcsh').   See source code at
  https://kernel.googlesource.com/pub/scm/utils/util-linux/util-
  linux/+/v2.22.2/misc-utils/getopt.c
