[gentoo-user] In need of script/command that will parse out all the packages from "emerge -avu world"

[Daevid Vincent]

Wondering if someone has a script or shell 'one liner' that can take the
output of "emerge -avu world" and make a list of the packages (I assume all
on one line). Then I could pump that back into "emerge -av" again (I don't
mind if it's a simple manual highlight and copy/append).

I didn't see anything here:

There is that 'pfilter' that looks interesting, but it's 2 years old, and I
can't get it to work :-\

For example:

daevid ~ # emerge -avu world | grep x11-
[ebuild     U ] x11-misc/util-macros-1.1.2 [1.1.0] USE="-debug" 45 kB 
[ebuild     U ] x11-proto/inputproto-1.4 [1.3.2] USE="-debug" 47 kB 
[ebuild     U ] x11-proto/xproto-7.0.9 [7.0.7] USE="-debug" 138 kB 
[ebuild     U ] x11-libs/xtrans-1.0.2 [1.0.1] USE="-debug" 97 kB 
[ebuild     U ] x11-libs/libX11-1.0.3-r1 [1.0.3] USE="ipv6 -debug" 1,415 kB 
...

I want to run some command that will give me a list like:

x11-misc/util-macros x11-proto/inputproto x11-proto/xproto ...

Then I could just select and copy that "string" and append it to "emerge -av
"
