sed or awk delete next line following patter

Hi,

I have the following formated file:

CONT_UK 10224
pemax
CONT_EC 10221
pemla
CONT_UK 10224
petem
CONT_SE 28000
laik


I need to delete all lines with the pattern containing CONT_UK, I need
also to delete the next line following that pattern. I can delete the
pattern matching lines:
$ sed -e '/CONT_UK 10224/d' contf.txt
pemax
CONT_EC 10221
pemla
petem
CONT_SE 28000
laik


, but how do I delete the next line following that pattern match:

So I end up with:

CONT_EC 10221
pemla
CONT_SE 28000
laik

Thanks for your help
Pete.

Quite easy, you append the next line to the current line then delete:

sed -e '/CONT_UK 10224/{N;d;}' contf.txt

awk '/CONT_UK 10224/{c=2}!(c&&c--)' file

Just set "c" to however many lines you want to delete, including the
line where the pattern was found.
