And i want to only output the first, second, and fourth line to another
file.

The:

sed -n '1,2p;4p' file.txt

doesn't work.

What magic do i need for it? :D

Thanks..:\



Perhaps you need to redirect the output to the second file :)

'>' if you can overwrite the second file:

sed -n '1,2p;4p' file.txt > 2nd_file.txt

or >> if you want to append to it:

sed -n '1,2p;4p' file.txt >> 2nd_file.txt


Cheers
