Prompting a user for a password within a script

Hi there --

I am writing a script that will provide a telnet connection to a remote server. What I need to do is have the user prompted for his/her password during the execution of the script. The shell that I am using is bash, and the OS is Fedora Core 2. What syntax would I user to accomplish this? Thanks.

You may want to look into the "expect" command, or maybe more simply the "read" builtin command from bash.

Hi there --

Thanks for your reply. I checked the system in question for expect, and it is not installed. I could go through the motions of installing it, but before I do, I would like to see if read would work in this scenario.

What syntax would I use for read in order to have the user prompted for a username and password once the telnet session is initiated? Thanks.

echo -n "Enter password > "

# the -s option will not echo the typed characters.
read -s password
