How to Delete Lines From File with pattern matching...

[skb2005]

I have a huge text file. I want to delete the lines starting with "::1".

Some one told me that I would be easy to do in the vi editor. I was wondering how?

In vi, at the ex command line
g/^::1/d

Note: there are numerious ways via shell and Unix tools. - And probably better if the file is huge, such as:
sed '/^::1/d' < /input/file

Cheers,

What about this ?
sed '/^::1/d' /path/to/input > output
or this ?
grep -v '^::1' /path/to/input > output

If you insist on vi:
:/^::1/d

Hope This Helps, PH.
