Question Extract Oracle home from Oratab and compare values
Friends,

I'm trying to do below in ksh script, while requesting user to provide src_db and dest_db values
1. Extract src_db and dest_db Oracle home from oratab file
2. Don't find db if it starts with comment (#)
3. Compare both values
4. Message success or exit with error if they don't match

Code:
Variables
=======
src_db = $2
dest_db = $4
oratab= /etc/oratab

Runtime
======
./compare_db src_db db1 dest_db db2

Output
=====
db1 = /oracle/app/oracle/product/11.2.0.3
db2 = /oracle/app/oracle/product/11.2.0.3
Success

I tried using sed from one of the other thread but not able to fit into my requirement,
any ideas or is it even possible?

Thanks.
