I have a script like
select * from table
!!
what those exclamation marks mean
are you sure you have only those two lines inside your script??
comment line perhaps??
Please post the whole script, not a fragment.
The "select" line looks like a bit of Oracle sql plus. i.e. not unix shell.
I think it could be
sqlplus user/passwd@SID << !!
select * from tab ;
!!
check the whole script please
