Not the way you're doing it. The easiest thing to do is to change your
data representation, rather than spending a lot of time trying to strip
whitespace. Try:
BLOCKED_SERVICES="tcp,111,Sun RPC:udp,111,Sun RPC:tcp,443,Microsoft
DS:udp,443,Microsoft DS"
IFS=:
for SERVICE in $BLOCKED_SERVICES; do
PROTOCOL=$(cut -d, -f1 <(echo $SERVICE))
PORT=$(cut -d, -f2 <(echo $SERVICE))
MESSAGE="$(cut -d, -f3 <(echo $SERVICE))"
for DATA in PROTOCOL PORT MESSAGE; do
echo "$DATA=${!DATA}"
done
echo
done
