Re^2: pattern matching question

thank you Kennethk. A follow up question. I am reading that the ^. is a metacharacter to indicated beginning of the string. So is if the variable is:

hostname.ms.com

is the ^. ignoring the "hostname" part of the string and just picking up the " .ms.com "? Also, why does the ^. have to be in brackets?

On the first position inside square brackets, `^` has a different meaning: it is a negation. So, `[^.]` means anything but a dot.	[reply] [d/l] [select]
