IO.popen puts

Hi,

i want to do a cvs login for a list of cvsrepositories
with IO.popen

the normal login via Windows shell looks like =

Y:\>cvs -d :pserver:username@cvshost:d:/cvsrepos/test login
Logging in to :pserver:username@cvshost:2401:d:/cvsrepos/test
CVS password: ********

i tried with =

cvsrepos=%w[test,test1,test2]
cvsrepos.each {|x|
  IO.popen("#{CVSEXE} -d #{CVSROOT}/#{x} login", 'r+') do |pipe|
pipe << "password"
pipe.close_write
puts pipe.read
end
}

but the script hangs with the output
CVS password:

What went wrong ?

Regards, Gilbert

just a guess:
1. try adding newline
2. try redirecting stdin on the command line without ruby (maybe cvs
reads the keyboard directly)

Found a working solution that is much simpler =

cvsrepos=%w[...]
cvspass=gets.chomp

cvsrepos.each {|x|
puts "Login CVS Repository >> #{x} ..."
IO.popen("#{CVSEXE} -d
:pserver:#{ENV["USERNAME"]}:#{cvspass}@cvshost:d:/cvsrepos/#{x} login")
}

the CVSROOT string takes a password too
