How to get a password from a shell script without echoing
Here is another way to do it:
#!/bin/bash
# Read Password
echo -n Password:
read -s password
echo
# Run Command
echo $password
The read -s will turn off echo for you. Just replace the echo on the last line with the command you want to run.
A POSIX compliant answer. Notice the use of /bin/sh instead of /bin/bash. (It does work with bash, but it does not require bash.)
#!/bin/sh
stty -echo
printf "Password: "
read PASSWORD
stty echo
printf "\n"
