Scrip writing for a password prompt

[menace212]

I writing a shell script to import a password on a password prompt.. How can I enter a password on a password prompt without typing the words in...For example if I do su -help the password prompt shows up. How can I import the password automatically into the script which then writes in when the password prompt shows up...Here's a example of my script or would I need to write this C


start="su -help"
export start

echo "Starting the user help"
$start echo
????????????(password prompt)

Um. I think your asking how to not echo chars that are taken as input? You either need to:
- put the terminal in "raw" mode for a little while
- use curses in C/C++
- rely on another program.

Note: putting su in a script or program is often a VERY bad idea.

If it has to be a script ask this in the unix script forum.
