I would recommend against using Artem's example of system("echo stuff | passwordprogram") since that will show up in the ps -eF output.... There are other methods open a pipe to a program where your password won't be viewable non-root users. In Perl you can use <code> open(HANDLE,">","|chpasswd") || die "$!\n"; print HANDLE "$username:$password"; </code> In PHP you can use <code>popoen()</code> or <code>proc_open()</code> I'm using v0.40 Passwd::Unix qw(uid encpass passwd) without any problems.

If I were writing new code though, I would give Passwd::Unix another try since the author rewrote it after my bug report. For reference, here's the code I've come up with: <pre line="1"> system("echo '$username:$password' | chpasswd") && die "Oops, there was some error setting the password!"; </pre> joe, yeah, I ended up writing my own version which has worked well so far.
