s there a way to automatically set passwords for accounts?

ie type /bin/passwd user password

instead of having to run /bin/passwd interactively? I`m attempting to write
a CSH script to create accounts and set default passwords.

No comment on your choice of language, but I'd be tempted to do it
in C and use the system calls. From memory, try "man putpwent."

Write a script in expect.

I'd use expect. Have a look at http://www.cme.nist.gov/pub/expect/

Hmm... I'm almost finished with a newusr command in C. My idea was to check
for evertyihg, including nfs mounted home directories, soft links to
home directory roots, and suggest home directories for users in certain
groups by checking to see where most members of a group currently reside.
After all, I won't be here forever, and after I leave, unix haters will have
to administer UNIX computers they know nothing about.

Anyways, if you are interested, I suspect I will have some functional code
finished by next week sometime.

BTW, who was talking about putpwent? Is that POSIX? I noticed that I have
it, but don't know if it can be used to create a new entry.

I think this Perl script would do it (no warranty what so ever, use at
your own risk). It's missing the ./ characters from the salt list.
Sample output:

% crypt_passwd testone2
ppHOs/VqtIKd.

-------
#!/usr/local/bin/perl

{

@salt = ('a','b','c','d','e','f','g','h','i','j','k','l','m',
'n','o','p','q','r','s','t','u','v','w','x','y','z',
'A','B','C','D','E','F','G','H','I','J','K','L','M',
'N','O','P','Q','R','S','T','U','V','W','X','Y','Z',
'0','1','2','3','4','5','6','7','8','9');
$salt_cnt = 62;

if($#ARGV != 0) {
print "usage: crypt_passwd passwd\n";
exit;
}

$input = $ARGV[0];

srand(time|$$);
$salt1 = int(rand($salt_cnt)) + 1;
$salt1 = @salt[$salt1];
$salt2 = int(rand($salt_cnt)) + 1;
$salt2 = @salt[$salt2];
$salt1 = "$salt1$salt2";
$encrypted = crypt($input,$salt1);
print "$encrypted\n";
}

Only problem that I can see is that passwd(1) tends to open /dev/tty
instead of relying on the current STDIO and STDOUT, usually for security/
spoofing reasons (similar to what is proposed here).

Easyest meathod would be to write a C or Perl application and use the crypt(3)
and getpwent(3)/putpwent(3) functions.
