Re: how to read STDIN interactively

Once you set $/ to undef, <...> will keep reading until the filehandle is exhausted. After that, you will likely need to reopen STDIN to start reading from it again.

No, not if STDIN is a terminal. Terminals automatically re-open, in effect. That's what you can rely on read functions to return EOF more than once, and why you sometimes have to signal EOF more than once to exit some applications.	[reply]
