Mask gets_chomp?

Ruby
1

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

How to adopt that for =

cvsrepos=%w[…]
cvspass=gets.chomp

cvsrepos.each {|x|
puts “Login CVS Repository >> #{x} …”
IO.popen("#{CVSEXE} -d
:pserver:#{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}
