I've installed qmail, and the docs say to test it using
and then something below.
how do i send this command? it seems to be something about "end of file" but nothing I found through google works, such as "look in your /etc/inputrc".
Also when I enter a command such as md5sum wihtout a filename, it sort of "freezes" as well. Would the "end of file" work here too?
Finally is there a way to stop whatever is happening on the command line before it finishes, such as a long compile process?
