Description Jonathan Kamens 2000-06-01 16:00:44 UTC
I have bash-2.04-3.  Watch this:

> sh -c 'FOO=~/scripts; echo $FOO'
/home/jik/scripts
> sh -c 'export FOO=~/scripts; echo $FOO'
~/scripts
> bash -c 'FOO=~/scripts; echo $FOO'
/home/jik/scripts
> bash -c 'export FOO=~/scripts; echo $FOO'
/home/jik/scripts
> 

In short, ~ is not expanded properly by bash in variable settings preceded
by "export" when bash is invoked as "sh".

This is such a weird bug that I can't believe it isn't somehow intentional,
but on the other hand, I can't imagine why this behavior would be
implemented intentionally.

Comment 1 Bernhard Rosenkraenzer 2000-06-26 19:51:37 UTC
I've forwarded this to the bash maintainers to make sure it's a bug before
fixing it.


Comment 2 Jonathan Kamens 2000-06-28 01:54:58 UTC
The bash maintainers claim that this is not a bug because the behavior is
required by POSIX, and when bash is invoked as "sh" it runs in POSIX compliant
mode.  I think that in this case, the POSIX standard is wrong, but it's unlikely
to change, so I suppose you should go ahead and close this as NOTABUG.


Comment 3 Bernhard Rosenkraenzer 2000-07-19 17:30:16 UTC
Yes, POSIX compliance is not a bug. ;)
