Sadly, no.  At least not with my experimentation.  If you use CDE (the Common Desktop Environment which uses .dtprofile) all sorts
of weird things happen to CDE if you exec or just call bash from .dtprofile.

Rather, you should just set the shell field in the passwd file.  Use the vipw command to do this. Change /bin/csh or /bin/sh to
/usr/local/bin/bash for the account you want, then exit.

If you don't know how to use vi, do a search on google.  Basically, the cursor keys will work fine.  Use i to enter insert mode
(there are all sort of other keys.) Press ESC to get out.  If you're not in insert mode, you can use x to delete.  When you're done
editing the file, press ESC, type in :x! and hit enter.  If you made an error and don't want to mess up the file, use ESC :q! will
exit and quit.

I don't think Solaris 2.6 has a chsh command sadly.

But, there is another trick you can do.  If your account is using csh, you can change the .login and .cshrc files on the last line
to say "exec bash" - it might work.  It's worth trying.

If you know shell programming you can add something like this to .profile. (This is off the top of my head, so it's likely buggy.)

First, go into bash. Then type in echo $0. This should print either bash or /usr/local/bin/bash.  The only box I have available now
as I type this (OpenBSD says "-bash")  Replace the bash in the if statement to this.

Put this line as the last line of your .profile

if [ "$0" != "-bash" ]; then exec /usr/local/bin/bash; fi

You might need to remove the exec in some cases.  CDE is a bit funny about changing the shell.  So again, don't do this to the root
account.  That way, if you get hosed, you can at least login as root and fix it. :)
