oracle startup problem

Got 8.1.6 running on solaris 2.6, on /etc/rc3.d/ S99dbstart startup I get:

+ /bin/su - oracle -c dbstart
tabs: cannot set tabs on terminal type sun usage: tabs [ -n| --file| [[-code] -a| -a2| -c| -c2| -c3| -f| -p| -s| -u]] [+m[n]] [-T type]

       tabs [-T type][+m[n]] n1[,n2,...]

after each component of oracle tries to start.

I don't understand because there is no "tabs" command ANYWHERE in any profile or script!!

TIA  cat S99dbstart
