More general zsh-scripting question

[Meino Christian Cramer]

Hi,

 for several software porjects avaible on the net I regulary update
 via cvs.

 Most of that projects dont need a password to login into their public
 cvs servers. Nonetheless it is tidy when you just wnat to run a
 couple of projects to press <RETURN> every time when asked for
 login:

 I am looking for a method to feed this <RETURN> into the login:
 prompt.

 For example these two lines are part of a function defined inside a script: 

 cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/snd login
 cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/snd update -d cvs-snd
 index=1


 When the second line is executed, the login: prompt stops execution
 of the script and waits for the <RETURN>.

 Is there a way to automate this ?

 Thank you very much for any help in advance! :O)

 Have a nice weekend!
 Meino

Why do you need cvs login in script? You only have to do login once, then CVS 
remembers login/password/repository combination and does not ask for it 
anymore.

if you still insist on it

expect
zpty module that is part of zsh

zsh has some examples of using zpty to drive interactive programs, like 
nslookup wrapper.

  As I mentioned I have a couple of projects from the net for which I
  do updates via cvs. Not all use the same cvs server. cvs only stores
  one login/password/repository combination.

Login is not needed with a reasonably modern CVS client.  Try this
instead (without login):

cvs -z3 -d:pserver:anonymous:@cvs.sourceforge.net:/cvsroot/snd update -d cvs-snd

Note the ":" after "anonymous".

Huh?  Are you using some odd CVS client?  The standard CVS client
has stored an unlimited number of login/password/repository
combinations for as long as I can remember.
