oldpassword -P

新密码

用户名和QUOT; ）;


但当然看起来没有用。


是否可以静默执行passwd命令，即没有

shell提示（两次）新密码？或者我应该完全看看

另一个方向 - 也许是通过编辑

/ usr / local / etc / passwd文件，是吗？

Happy New Year and all that!

I''d like to write a short PHP script that will allow users to alter
their virtual server password via a secure web form. I had hoped that
I might be able to call the shell passwd command from PHP, something
like this:

exec( "passwd -O $oldpassword -P $newpassword $username" );

but of course that doesn''t seem to work.

Is it possible to execute the passwd command silently, ie without the
shell prompting (twice) for New Password? Or should I be looking in
another direction altogether - perhaps by editing the
/usr/local/etc/passwd file instead, yes?

Some advice would be greatly appreciated, thanks.
