Hi All,

Please help

1. Single pattern
grep -v "FLIGHT PLAN" file_name

above command will only print the lines which does not have the given pattern ..

-v -> inverts match.

2. Multiple pattern
grep -v -e "pattern1" -e "pattern2" file_name

If a line does not contains any of the given pattern then it will
show that line. This may also help you.

Code:
sed '/Ex.FLIGHT PLAN/d' filename > newfilename
