mask gets_chomp ?

[Rebhan, Gilbert]

Hi,

i have a script that uses a password as input.

The password is provided via gets_chomp
in the shell.

Is there a way to mask the password with *
or do i have to write a gui for that ?


Regards, Gilbert

Maybe you can do that via curses. Other than that, you could use "stty
-echo" before and "stty echo" after the password input:

14:50:07 [~]: ruby -e 'system("stty", "-echo")

puts "enter!"
pass=gets.chomp
puts "You entered #{"*" * pass.size}"
system("stty", "echo")'

enter!
You entered ******
14:50:56 [~]:

Kind regards

robert

How to adopt that for =3D

cvsrepos=3D%w[...]
cvspass=3Dgets.chomp

cvsrepos.each {|x|
puts "Login CVS Repository >> #{x} ..."=20
IO.popen("#{CVSEXE} -d
server:#{ENV["USERNAME"]}:#{cvspass}@cvshostd:/cvsrepos/#{x} login")
}
puts "Login successful !!"


the password is readable in the cmd shell

Just in case, are you aware of HighLine's ask mehod?

require 'rubygems'
require 'highline/import'

pass = ask("Password: ") {|q| q.echo = false}
