[ale] Reverse of the 'cut' program

[Justin Goldberg]

I am trying to parse a log file and exclude the lines that contain any one
of a few different strings, for example "don't show ones that contain
google.com or ones that yahoo.com" for example.

I'm guessing that sed or awk would fit this purpose.

I looked on the web but didn't find any examples that made sense to this
Linux newbie.

Any replies or pointers will be greatly appreciated!
