I was wondering if it is possible to change a users password by redirecting
input from a data file. At our installation, there are about 40 temporary
accounts that need to exist, but because of problems that we have been having
with them, we would like to set up a cron that would change the password
as needed. The cron part is easy, but getting the passwd program to
recognise the input redirection is what is giving us the program. Does anyone
have any ideas?
Ideally we would want something like this:
#changepw "oldpasswd" "newpasswd"
that would go through all of the desired accounts and change the passwords
to those directed.
BTW, we are running SunOS 4.1 on a Sun SparcServer 4/490.
Thanks in advance,
Glenn

Ideally you would want to read the user name, old password and
new password from a data file. The reason is that ps would
be able to see the passwords as they were changed.

I've written a utility which does exactly what I described above.
It does not work with SunOS (because of passwd.adjunct), but does
work with V7-format /etc/passwd, and SVR3.2 or SVR4-format
/etc/shadow files. You pick which one you want at compile time,
and it gives that variety to you. The code figures out the
difference between SVR3.2 and SVR4 /etc/shadow files (sort of,
it may have problems I don't know about just yet ...)
Depending on how many requests I get I'll either mail individual
copies or post the code to alt.sources.

Well, I got a number of requests, so I just posted it to alt.sources.
