I make extensive use of the functions to navigate through the command history in my terminal; I wonder if there is some way to navigate the command output history as well? (besides keeping a large histsize and leaning on the pgup key)
I cannot just 'rerun the command', as in my particular situation the source of the commands changes; I frequently need to look back at the output of a previous change.
Hacks welcome.
Thanks!
Edit 2010:
I've given 'tee' the credit; among all the methods to log your session elsewhere, it's the most broadly applicable (i.e. it's part of gnu coreutils, and doesnt require a specific shell or utility to work). It wasn't really what I was looking for, but I realize that such a thing doesn't really exist.
The closest approximation I can think of is to use something like screen
(byobu/tmux) that logs to file, and write (and keybind) a custom command to page/search through that logfile (think less
paging by prompt rather than screen). Thanks everyone.
Edit 2012:
@Dustin Kirkland's answer is clearly best, at least generally; the terminal's scrollback buffer is least-intrusive way to navigate command output history. Byobu appears to have a large default number of history lines saved (10K; tmux has 2K, GNU screen 100), and it allows regex searches (a cursory look indicates that GNU screen has no scrollback search, and tmux has only plaintext search).
