Unfortunately you didn't use one of the standard bug report tools (e.g.
reportbug), now I have to ask you what shell you're using, as at least
with bash it works just fine:
$ bash
$ FOO=123 BAR=xyz bash
$ echo $FOO
123
$ echo $BAR
xyz
$
Also with ash (another POSIX shell that's used a lot) no problem:
$ ash
$ FOO=qwe BAR=098 ash
$ echo $FOO
qwe
$ echo $BAR
098
It is immediately obvious that there are no ";" between the variables,
so it can't work !
All that's obvious to me is that you give too little information;
without semicolons in CAN work. That's also why no one responded to your
message on the mailing list, as no one has this problem.
So please give more info about your system, most importantly your
default shell.

That is strange.
I have this problem on 3 systems. 2 of them run openSUSE, the other
one runs debian lenny. I haven't done anything to the shell's
configuration on these systems, standard install.
1) openSUSE 11.2 (real computer)
shell: BASH version 4.0.33(1)-release (i586-suse-linux-gnu)
SHELL=/bin/bash
SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor
perl: v5.10.0 built for i586-linux-thread-multi
Linux --- 2.6.31.5-0.1-desktop #1 SMP PREEMPT 2009-10-26 15:49:03
+0100 i686 athlon i386 GNU/Linux
2) debian lenny (virtualized)
shell: BASH version 3.2.39(1)-release (x86_64-pc-linux-gnu)
SHELL=/bin/bash
SHELLOPTS=braceexpand:emacs:hashall:histexpand:history:interactive-comments:monitor
perl: v5.10.0 built for x86_64-linux-gnu-thread-multi
Linux --- 2.6.18-028stab064.8 #1 SMP Fri Nov 6 11:28:25 MSK 2009
x86_64 GNU/Linux
On both systems assigning multiple variables by hand works, but it
doesn't work with the pre/post scripts unless I add a semicolon as
described before.
I've had a look at the code again, especially at "scriptrun". It boils
down to this:
--- code ---
#!/usr/bin/perl
system("/bin/bash -c 'FOO=123; BAR=456 echo \$FOO>>./out.txt'");
--- code ---
If I run this test code on _any_ linux system that I have access to
(home, webserver, uni) '123' will _not_ show up in 'out.txt' if I
remove the ";" !
So from my point of view the problem is quite real. Does anybody
actually use the Dirvish variables and can report it works without ";" ?

Robert
