removing multiple lines of text in a file
Hi,

I'm trying to remove multiple lines of text based off a series of different words and output it to a new file

The document contains a ton of data but i want to delete any line that has the following

mx1.rr.biz.com or ns2.ri.biz.com

i tried using grep -v filename "mx1.rr.biz.com" > newfile

How would i go about doing this?

Or, a very slight modification:

Code:
grep -v -e "String2remove1" -e "String2remove2" ... -e "String2removeX" file2operateOn > newFile

So, something like...

Code:
grep -v -e "mx1.rr.biz.com" -e "ns2.ri.biz.com" filename >  newfile

...should do the trick.

Everyone of those solutions works

grep -v -e "mx1.rr.biz.com" -e "ns2.ri.biz.com" filename > newfile

does exactly what i wanted, thank you.
