This is an updated version of a script to assist with entering (for
example) the 4th, 7th, and 11th characters of your password.
Example usage:
./passchrs 4 7 11
The script will then prompt for your full password and display only the
appropriate characters. This updated version does not show the password
as it is typed.
Cheers.
#!/bin/bash
echo -n password:
read -s PW
for P in $@
do
C=$((P-1))
echo -n ${PW:C:1}
done
echo
