Neat. So when my terminal is spewing output because I ran "cat massivefile" instead of "cat massivefile | head", I can hit ctrl-D to stop it instead of repeated

Neat. So when my terminal is spewing output because I ran "cat massivefile" instead of "cat massivefile | head", I can hit ctrl-D to stop it instead of repeatedly hitting ctrl-C and despairing.

I don't think so, since cat is reading from massivefile, not from your tty.

No, thats what ctrl-s and ctrl-q are for.

  Back in the day, using a slow modem or teletype, discard (flush output) was super important, but several years back when I hooked up an actual Wyse dumb terminal to a Linux box I was dismayed to discover that it's actually not implemented in Linux.

  Nice. Reminds me of using the "stty -a" and "stty <some_param>" commands many times on Unix terminals, back in the day, for some of those settings you list, also for things like CR/LF translation (ocrnl, onlcr, ...), raw, sane, ...

Also, a side note, I would rather just run "head massivefile" or even better "less massivefile" (because, most probably I'd want to see past what head shows by default). Running cat and then piping it to another program is inefficient, 2 forks + pipe.

  And on systems where head was not present (seen some earlier), but sed was, you could do: sed nq file where n is some positive integer, to print the first n lines of the file. Also, body (the complement of head and tail :) # body sed -n $1,$2p $3
