copy lines containing word from one file to another file in linux

Question

I want to copy lines containing certain words from file1 to file2.

Suppose file1:

ram 100 ct 50
gopal 200 bc 40
ra         


        

Answer 1

I know I'm late, but just wanted to add that you can do this in vim. Create a copy of the file, then run

:g!/pattern/d

(delete all lines not having the pattern)

so,

:g!/^\w+ \d+ ct \d+/      \\ view the lines
:g!/^\w+ \d+ ct \d+/d     \\ delete lines
