Perl Grep and Map

13 points

All,

I have an array whereby each element in that array is of the following format:

@myNames = ('a b', 'c d', 'e f', 'g h', 'i j');

However, I am only interested in grepping the second part of each element - i.e. b, d, f, h and j.

How do I grep for second part? Would Map be helpful?

I get the entire element returned and not the section of that element that I am after.

I am trying to replace specific text within several files (maybe around 200 files). Is there a way that I could this without having to replace the text manually.

I am actually trying to change the IPs in several httpd.conf, eg. 192.168.0.5 to 192.168.0.10. I have googled and some of the sites suggested using grep and awk, but no specific help was found by me.

Any help is greatly appreciated. Thanks.
