If you like, you can use something like "expect" to script your dsmadmc
commands.  For applications that block regular STDIN piping and redirecting,
like telnet or dsmadmc, "expect" does the magic tty swapping that's
necessary to feed the password into the password prompt so it won't show in
the ps.  I don't know much more about it because it's a little higher
powered programming than I've done in years, but if the security is that
important to you, it might be worth your time.  Here's the web site.

There's also a Perl version, but I don't know how good it's cross-platform
functionality is.

Good luck.
