This has taken me some time to figure out because I couldn't find anything on Google. I think the problem was that I didn't know what to look for.

If you have a bash script that asks the user to enter their username and password you use the read function in sh. But when you read in the password you don't want it to show on the screen what you're writing. Someone could be leaning over your shoulder. Python has a similar standard library module called getpass which works like this:

>>> from getpass import getpass
>>> p = getpass("Password please: ")
Password please: 
>>> print "Your password is", len(p), "characters long"
Your password is 5 characters long

That's fine if you do this via Python; but I needed to do it in one of my bash scripts. Here's how to do it:

#!/bin/bash
read -p "Username: " uname
stty -echo
read -p "Password: " passw; echo
stty echo

Now, hopefully this will help other people who get stuck with the same problem.

Nice, first hit on google for "bash read password" and exactly what i need :D

Easier solution:
read -s -p "Password: " passwd
see also: the description for builtin commands in the bash man page (man bash or info bash)

also interesting is read -e ... to gain readline support for editing the input line

Note that you actually don't need to handle the terminal options with stty yourself -- the bash read builtin has an option that will do it for you [-s]. See http://www.ss64.com/bash/read.html for the other options for the read builtin.

The following example should be functionally equivalent to yours:

#!/bin/bash
read -p "Username: " uname
read -s -p "Password: " passw

Definitely a cleaner solution. Had I only known!
Richard Bronosky - 25 March 2009 [«« Reply to this]
Before doing a "stty -echo" or a "read -s", you should set trapping like so:
trap "stty echo; exit" INT TERM EXIT

Otherwise the script can exit in a state where the user can't see there keystrokes and then they get confused.

I constantly am getting this error:

read -s -p "Password: " passw
read: 4: illegal option -s

does anyone know why I can't get -s to work?

Hi Matt!

In a script, start with

#!/bin/bash

instead of

#!/bin/sh
