Re: Strange variable asignement in bash script

[Pete Dumpert <pdumpert@innovativebusiness.net>]

If what you are trying to to is to create a bunch of variables, here's one way:

TMPFILE=/tmp/xxx
TEST="service1 service2 service3"
HOSTS="server1.mynet server2.mynet server3.mynet"

touch $TMPFILE
for I in $TEST
do
  for J in $HOSTS
  do
    ...
    echo "${I}.${J}=\"some value\"" >>$TMPFILE
  done
done

. $TMPFILE
rm -f $TMPFILE
