Interactive Commands

Hi, I was recently doing useless stuff with System(), Exec(), Passthru, etc... and was wondering if i could change my password using this : I tried : echo "<pre>"; passthru("whois devhome.net"); echo </pre>"; this works fine, but i can't seem to get this right : echo "<pre>"; passthru("passwd\noldpass\nnewpass\nnewspass"); echo "</pre>"; why doesn't this work, i'm not very familiar with how to do interactive stuff... and how can i read the output and on that basis make my decision.... maybe if it says password too easy... but still i'll keep on doing that... thanks. ===== To Find Out More About Me : http://mukul.tsx.org/ __________________________________________________ Do You Yahoo!?
