Unix nerdery
Oh, how shall I reverse the order of lines in a file?
In Vim:
:g/^/m0
(thanks, Vim manual chapter 12!)
From the shell:
tr "\n" "#" < myfile.txt |rev|tr "#" "\n"|rev
(Watch out for #s in your source file)
(thanks, Lonneke!)
Update: GNU Textutils includes tac (cat backwards…) which reverses the lines of its input.
