how can I change the default shell which comes up when you start the terminal for the1st time in open solaris
also is it possible to apply this to the new users so they get a defined shell when their account is created ?

while creating a new user we can specify like this

# useradd -u userid -g gid -d directorypath -m -s shell_environment Username

in shell environment for
bash - bash
borne - sh
korn - ksh
c - csh
