You should be able to manage editing "/etc/passwd", etc. with `mv',
`cat', etc. then. ;)

OK, so that's definitely a Digital Unix of some flavour. Try
`/sbin/bcheckrc' as someone already suggested. Note that ${PATH} is
unlikely to include /sbin in the single-user mode shell which is less than
useful -- I find it silly, but that's required for Bourne shell for some
standard conformance I would guess.

Yes, it is like this with DU -- the root filesystem (if separate --
that's what you need to check "/etc/fstab" for) is pretty minimal. You
need to get the system to mount /usr before you proceed.
Note that if the system's got C2 security enabled then password
information is managed in a database outside "/etc/passwd" and
"/etc/shadow" and you'll have to poke at that database to get the root
password reset. After over 10 years I don't remember the details anymore
and chances people here may not know them either as this is considerably
away from how Linux does things.
I suggest you check with a DU/Tru64 mailing list indeed or try system
documentation available online. It should be much better than the bits
around the SRM console which I always found a little bit obscure and
scattered around.
Good luck!
