Re-arranging lines of text... help?
Hello,
I am new to Linux, and I am learning slowly but for surely. I am trying to currently figure out how to go about re-arranging lines of text of a *.txt file... Like for example:
Say pool.txt has 20 lines of text, and the last 5 lines of text I want to move to the top of the *.txt file and take the first 5 lines of *.txt file and move them to the bottom (more less swapping the lines) and then save it to a different file name to pool2.txt, how would I go about doing that?
I thought just by using the command cat > pool and typing whatever it is I needed, and then ctrl+d so that it enters, I know I did that correctly because when I type in the command cat pool it shows up. But when I try to take the lines I want to swap in place with, within that file it doesn't seem to work.
What am I doing wrong? Any suggestions?
