print all even lines of a txt file
In other news, I have a colors text file with hundreds of lines, and I want to print only the even numbered lines. for example I have this file looks something like this:
ALLCOLORS.TXT
red red green red
blue red red red
green red red blue
green green green
blue blue blue
red blue blue blue

and I want a command that outputs something like this:
ALLEVEN.TXT
blue red red red
green green green
red blue blue blue

Another way of asking this is how do I delete all of the ODD numbered lines out of a file?? Thanks again!!! I love this place!
