Package: ash
Version: 0.5.4-12
Severity: normal
Hiya,
$ ash -c '. -- --help'
.: 1: --: not found
The handling of "--" is mandated by POSIX I beleive.
With ksh, pdksh, bash and in a POSIX script in general as POSIX
allows any "." implementation to recognise options, you have to
use:
. -- "$1"
if you can't guarantee that "$1" won't start with a "-".
Unfortunately, that code doesn't work with ash, so a POSIX
script written in such a robust way will fail on those systems
where ash is the POSIX sh interpreter.
Best regards,
Stephane

Hi Stephane,
the dot special builtin doesn't know about the -- option according to
posix, and 'conforming application shall not use that argument'.
