[gentoo-user] Output of "emerge -NDpvu world"

[econti]

Hi all
is it possible to page the output of "emerge -NDpvu world" in a terminal?
'emerge -NDpvu world | more' does not work.

If you use screen you can then use the scrollback it provides

Hmmm, whatever you set it to, you will be a few lines short.  The error 
will always be just above what you can scroll back to.  lol

Of course I've noticed it, how could I not?  (Murphy's law has *so* many
corollaries.)

When I really want it, for any given command, I use bash with
     command 2>&1 | tee /tmp/junk
and this suppresses most color-coding so I can view the results with simple
tools.

It helps to have a really big /tmp (mine has 19GB free at the moment), and
to keep
using the same name in case you forget to delete the (possibly huge) file.

I've never understood why distro's still bother with more, it's so 
impractical.

Lowest common denominator. Like vi, it may be crap but all Linux installs
are expected to have it.

Hm.  Works for with either more or less.

What do you see if you do "emerge -p system | more" ?

If using less(1) or more(1), I would do it this way
   emerge -NDpvu world 2>&1 | less
under the bash shell.

There are a lot of advantages to less, but perhaps the most important is
that you can scroll backwards if you've gone too far -- you don't have to
start over.
