!! what is this means

I have a script like

select * from table

what those exclamation marks mean
# 2  
are you sure you have only those two lines inside your script??
# 3  
comment line perhaps??
# 4  
Please post the whole script, not a fragment.
The "select" line looks like a bit of Oracle sql plus. i.e. not unix shell.
# 5  

I think it could be

sqlplus user/passwd@SID << !!
select * from tab ;

check the whole script please
