Hi, Suppose there is a string "var = 123", I want to substitute 123 by 456, then I have to write like this "s/(var\s+=)\s+\d+/\1 123/". Is there a way so that I can combine ' ' into the parenthesis as "s/(var\s+=\s+)\d+/\1456"? I know \1456 is not correct, but how can I seperate \1 and 456 without using a space? I hope I have made myself understood. -- Zeng Nan Simple is Beautiful. ~~~~~~~~~~~~~~~~~~~~ PGP Key: http://hobbit.homeunix.org
