All:
 
I am trying to write a bash script that prompts a user for a password if
they want to run a specific function. I was able to encrypt the password so
that users cannot just 'more' a file and see the password, but when the
script is ran and it prompts for a password, it shows what they type on the
terminal. How do I change this so that their input is not displayed on the
screen for this line? I figure it is probably a single command, but I don't
even know where to begin to look.
 
Any help would be appreciated.
 
TIA

Thanks,
Chad M Truhn
