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?

fmt
fmt(1) General Commands Manual fmt(1) NAME
fmt - format text SYNOPSIS
width] [file...] DESCRIPTION
The command is a simple text formatter that fills and joins lines to produce output lines of (up to) the number of characters specified in the width option. The default width is 72. concatenates the arguments. If none are given, formats text from the standard input. Blank lines are preserved in the output, as is the spacing between words. does not fill lines beginning with a period for compatibility with Nor does it fill lines starting with Indentation is preserved in the output and input lines with differing indentation are not joined (unless is used). can also be used as an in-line text filter for the command: reformats the text between the cursor location and the end of the paragraph. Options recognizes the following options: Crown margin mode. Preserve the indentation of the first two lines within a paragraph and align the left margin of each subsequent line with that of the second line. This is useful for tagged paragraphs. Split lines only. Do not join short lines to form longer ones. This prevents sample lines of code, and other such "formatted" text, from being unduly combined. Fill output lines to up to width columns. WARNINGS
The width option is acceptable for BSD compatibility, but it may go away in future releases. SEE ALSO
