How about something like this:
Code:
#! /usr/bin/ksh
IFS=:
exec < /etc/oratab
while read Oracle_value junk ; do
firstchar=${Oracle_value%${Oracle_value#?}}
[ $firstchar = '#' ] && continue
echo Oracle_value = $Oracle_value
done
exit 0

Oracle_value=`cut -d : -f 1 /etc/oratab | grep '[A-Z]+' | sed 's/\n/ /'`
in this cut will isolate the first column in all lines using : as separator and [A-Z]+ in grep ensures that you dont read the columns having # etc and sed replace newlines with spaces. If you want a loop in which you can pass the content of whole lines having QBIP etc. You may try this.. while i in `grep '^[A-Z]+:.*$' /etc/oratab` do echo $i done this will echo only those lines beginning with all caps and ending with a : . So effectively isolating those lines containing QBIP etc.
