I know csh is the shell of choice on FreeBSD. But I have this question on Korn Shell and it would be great if somebody could explain. Can someone tell me a little more about the Korn Shell [[ ... ]] double-brackets construct used for comparing string expressions. How does it differe from the standard [ ... ] single brackets. You could tell me to RTFM but I haven't gleaned enough clarity from such efforts already expended. It would be great if you could give some idea through examples. Cheers, Andy --
