Greetings, All!

This has been plaguing me for several years, but only now I got to test it
more thoroughly.
Shame on me.

$ /usr/bin/getopt --options '+H' --shell sh --name x -- -d
getopt: unknown option -- d

Expected output:
x: unknown option -- d

$ /usr/bin/getopt -V
getopt from util-linux 2.25.2

Poked around,
getopt from 2.20.1, 2.27.1, 2.31.1 and (reportedly)2.33 works as expected.

Is there a chance for an update?

2.27.1? Typo?

See:
https://stackoverflow.com/questions/43078330/how-to-use-the-name-argument-to-getopt
( How to use the --name argument to getopt? )

"This is a bug (or just a non-portability issue) which is already fixed in
util-linux 2.28, by commit 30fbf2f6. Before this fix it worked only on Linux,
OSX and a few BSD flavors but not on WIN32 or GNU-Hurd for example".

The answer by "rudimeier" also decribes a temporary work-around.

Regards,
Henri

No, just a different OS.
