Use a different live distro, one that includes all you need - such as System Rescue. I think Arve's suggestion of using screen (or tmux) is the simplest effective solution. I routinely run emerge -a @world in a tmux session, and scrolling back though long update lists is easy. -- Neil Bothwick I spilled Spot remover on my dog.

I think "fail" is the wrong word here. My own scripts send such quest-
ions to the same device they retrieve the answer from ("/dev/tty" in my
case). So both, question and answer would be missing from the log file
produced by "tee", but they would appear on the screen, which seems more
important to me.
But you are right in that it would at least be difficult to have them in
both places.
Sincerely,
Rainer

However, I'd like to keep things as simple as possible, be- cause an important usecase for me is installing a new or fixing an ex- isting system after booting from a USB stick. The "script" binary is in package "sys-apps/util-linux" which belongs to "@system", so it SHOULD be on my USB stick. Like "cmp" and "diff" from package "sys-apps/diff- utils" which belong to "@system" too, but which were NOT on my USB stick when I used it to install my current system about three years ago, or at least they were not in "PATH" (I then didn't frantically need these, so I didn't really search for them). I do not know what "nano" (the only editor then available) will do with all the control characters in the "script" output file, and "scriptre- play" doesn't seem to offer any interactive control. I do have a "gawk" based shell function which turns a "script" output file into a normal text file containing command log + standard output + standard error sans any control characters, but this will not yet be available in that situ- ation. So I'm still preferring "tee" here which definitely WAS on my USB stick. Sincerely, Rainer

I'm guessing any proposed solution would fail when what you want to capture has an interactive component like this. My solution would rather be to run your emerge commands in a place that would give you the scroll-back that you lack now, such as in a screen session. It feels like something like a screen session would be potentially beneficial in more ways as well, such as being able to do this remotely. Regards, Arve

Running "emerge -p ..." followed by "emerge ..." without "-p" would run the dependency analysis twice for EVERY package update. Using a single "emerge -a" call will run the dependency analysis only once for almost each package update. The option to say "N" and further inspect the "em- erge" output using an editor is meant as sort of a safety belt which is not intended to be used on a daily basis. > I haven't dug into the man page, but I'm sure there are also options > that are more intended to make the output more suitable for > parsing/etc. A quick search in the "emerge" manual page for "pars" and "pip" did not turn up anything I considered relevant. Can anyone give more hints? Sincerely, Rainer
