Re: hiding input text

[Swen Thuemmler]

What's wrong with stty -echo? Ok, it is not portable (works only on Unix),
perhaps someone has a portable solution... Here is a quick and dirty
getpass function. It should perhaps have a trap to restore the terminal
modes on exit. And I found no other way to get a newline in a string than
to use single quotes (I tried \n and echo but did not succeed).

Hope this helps

#!/usr/bin/zsh

function getpass() {
  echo -n "Password: "
  stty -echo
  key=""
  end='
'
  while ( true ); do
    read -k key
    if [[ "$key" == "$end" ]]; then
      break
    fi
    echo -n .
    pass="$pass$key"
  done
  echo
  stty echo
}

getpass
echo "Password was $pass"

hiding input text

[Jason Zapman II]

I'm attempting to write some front end scripts for some programs that
require passwords.

I would like to query the user for these passwords, but not have what they
type be displayed.

Can zsh do this, and if so, how?

(And if not, it would probably be a VERY useful thing to impliment)
