I asked because the regexp can be made simpler then. Try what I committed.

I still don't get the implication of the question---what does it 
matter what type of regex it is if that is what is properly expected 
by expect, the target at hand?



In any case, afaik, expect uses Tcl regex, which is a superset of POSIX.



Thanks.

No, my question was if these are really extended regexps opposed to 
POSIX regexps or some homebrew placeholders.

I'm not sure from what angle you're asking, so forgive me if the 
answer is simplistic.



Yes, that's the regex needed to have expect properly match both 
responses "Retype new password" (my system's) and "Retype new UNIX 
password" (current passwd HEAD's) as the prompt to confirm the new 
password. The other patterns are presumably for other *nix flavors.

I don't know anything about expect, are these normal regular expressions?

The "Retype new UNIX password" prompt can also be "Retype new password"
