eval can be used to set more than one variable in a single command. This
is used by e.g. ssh-agent.
# Using a separate function for slightly more clarity
domain_parser() {
echo $1 | sed -e
's/^\([^.]*\)\.\([^.]*\)\.\([^.]*\)\.\([^.]*\)$/hostname="\1" ; domain="\2";
top0="\3"; top1="\4"/'
}
eval `domain_parser $NEWDEV`
But then, why do you assume a domain name has exactly four elements?
