Nobody cares about compatibility with Bourne shell any more. Not since
Solaris finally pulled its head out of its ass and put a POSIX sh in
/bin (20 years after everyone else)
Well, to be strictly conformant with heirloom SysV sh, we have to use the
following (which is uglier than Cobol with a hangover):
#looper2-sh.sh
n=4
i=1
while [ $i -le $n ]
do
echo i = $i
i=`expr $i + 1`
done
which also works with dash and mksh. Perhaps this needs to go into a FAQ

Brace expansion is done before variable expansion:
