If you want to cut the first 9854797 lines of one file, and put them at the beginning of a 3023304 line file, opening them both up in vim and cutting and pasting from one to the other is probably not the most efficient way to do it. It’s been pasting for a while, and my load average is up over 8 and I’m using 1.4Gb of swap.
Maybe I should kill this and figure out how to do it with awk or something.
