Re: [TUHS] manual humour (was tunefs -m 5%)

ed was my goto over any modem, it's very undemanding in terms of characters transferred. Can't tell you how many times I've done ed foo.c /^some_function 20p goto the line c whatever . w q So a lot of use so long as I was using dial up, some continued use when I was doing bring up and the tty driver was all screwed up so you are typing at some slow console. Once performance wasn't an issue, it was vi all the time. I did a year in emacs, never warmed up to it, I know some people love it, I MUCH preferred the way vi works. So back to vi, some time spent in xvi because I was on 4MB main memory Sun machines so I made a version of libc that treated \n like normal libc treats \0, then changed xvi so it used mmap(2) to map the file instead of reading it in and strdup()ing every line. I did that because I was looking at performance logs and the very most I could fit into memory was 1/2 of what I could fit into memory with mmap(). That 2x bigger was a big deal to me, I was in out of those logs all the time. xvi also had buffers, like emacs, you could be looking at 2 files at once or 2 different regions of the same file. Then vim came along and it had everything I wanted and I didn't have to support it so I have been in vim since 1996 (that's the last time the xvi source that I have was touched). If things get wonky, ed still works, which is pleasant. But 99.9% of the time I'm in vim, I'm in it right now, typing this. I still use mutt(1) as my mail reader and I wacked it to drop me into vim.
