Korn shell [[ ... ]] operator
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
