Entering secret password
Hello All,

I am trying to write a script when executed, asks you for the password, and confirm password; it should save to a file and also entered password should not be in clear text on the console - should be as ****

Can somebody give me direction in writing this in shell?

Thanks
Chiru

Code:
echo "Password\c"
stty -echo
read passwd
stty echo
###### go on from here

I do not think there is a way to do the * thing in POSIX shell.

Thanks Jim,

What should I do to have the password to be entered on the same line as the echo "Enter Password"?
when I use echo and then read line, the prompt for entering the password is going to the next line.
Will \c do that for me, because when I say echo "Enter Password\c", it is printing as: Enter Password\c

Thanks,
Ravi

Jim,

Are you using csh/tcsh as your shell?

these shells have thier own echo as a built-in command.
simply use /usr/bin/echo or /usr/sbin/echo instead of echo
and the \c should do what you're looking for.

csh and tcsh doesn't support the \c option.

1. it's ksh
2. echo "some strings \c" keeps the output on the same line as the input
3. "which echo" returns /usr/bin/echo
4. csh is not POSIX, and I do not recommend using it for a variety of reasons.

Most of here do not assume csh in our posts. The OP may be using csh, you are right
