Some trouble with su in script

[Ogzilal]

Hello world,

I have some confusion with su command in a script.
Im loggin as root and execute the following command :

su - oracle <<-!
grep 'some text' /etc/oratab
if [ $? -eq 0 ]
then
print "some text found" in /etc/oratab
else
print "some text not found" in /etc/oratab
fi
!
some text found in /etc/oratab

but my /etc/oratab does not contain the pattern "some text"

Another variant is

su - oracle <<-!
grep 'some text' /etc/oratab
print "exit status of grep = $? "
!
exit status of grep = 0

but my /etc/oratab still does not contain the pattern "some text"

Question : How can I get the right exit status of grep command within the su ?

-eq is to compare strings, try using the =, the integer comparator (is that a word?).
