I tried looking around in the forums, but didn't know exactly what wording to use to search for this particular query so sorry if this is a dupe.

When I install many programs at one time, or emerge -avuDN world for instance, after a while the screen history is erased and I can't see what the interaction comments were above.

i.e.
* You need to do this to make this work etc etc..

Is there a way to report on all the comments for your previous emerge?

Well, there's a console way, and an xconsole way. On the console, you
can do
Code:

emerge <whatever> 2>&1 | less


If you hit 's' less will save the output as a file.

In X, just set a ridiculously high history buffer on your terminal program, and scroll away.

There may be better ways. With less, the disadvantage is that is stops at the first screenful, unless you hit 'F', then it will follow the output once you've caught up.

So then I guess I could grep that output with *Or maybe because the lines are in a particular colour, grep by certain colours, is that possible?

Well, you can colorize grep. It's pretty limited, basically just highlighting. But grepping the actual color codes? Is that what you mean? I'm sure there's probably some way to do that. You could tell grep to treat the file as binary. Why would you want to though?

Basically, rather then sift through previous emerges, I just want to make it easy to quickly see, if the program required me to change anything manually.

From what you've given me i've devised this:
e.g.
Code:

# emerge sun-jre-bin 2>&1 > emergelog.log && cat emergelog.log | grep "*"


This will perform the emerge, and show all the comments involved..
Do you think that's the easiest way to pull it off? I would also like to be able to see the emerge (as normal) if possible and also log it to a file. I'd prefer not to interactive with less as you have to manually save it.

Is there anything I can use to save it to a file with the date?

Yeah. That works.

The thing is, I though you wanted to grep for the control characters for
color, not the colors. I.e. ^[033 instead of the color yellow.

I don't know why I thought that.

lol nah was just thinking of a different way to grep the comments but * seems to work fine!

No idea on how to automatically capture the output to a filename with the date inside it?
