Right. I was referring to the shell shortcut "$(< filename)". Simple - Useful - and probably forgotten by the time I need it again.
That's the same thing I meant. It is $(command) which is the same as `command` where the output of the command replaces it on the command line before further evaluation. That's something you can use frequently. And '< filename' to control i/o redirection is something you can use even more frequently. So it's like doing '20i- <esc>' inside of vi to insert a dashed line. You don't have to know specifically that you can give a count with the insert command, you just know you can combine a count with any command.
I see. I haven't done any serious shell programming in years, so I've forgotten most of the little stuff like this (if I ever knew it to begin with).
