A way to display required update count in notifications?

[xanrer]

Is there a command in Gentoo that shows how many updates available at that second, I don't mean the names of the packages I just need the exact number. If there is no command like that no problem either, I can just use `emerge -pv @system | grep Total` too but it wants sudo permissions and the implementation I found is outdated. What I want to do with this information is to send it through notify-send and when I press a certain key combination it just sent me the number.

Please don't use emerge -pv @system for any existing system as it is pointless.

If anything, one should use emerge -pvuDU @world, optionally with --getbinpkg=n if binpkgs are default on, to test for updates.

I got an interesting and really long output from `sudo emerge -pvuDU --getbinpkg=n @world | grep Total`

Firstly, `Total: 119 packages (5 upgrades, 1 downgrade, 109 new, 2 in new slots, 2 reinstalls), Size of downloads: 524498 KiB` it says here 109 and `sudo emerge --sync` doesn't update anything. I thought I made everything binary but seems I somehow failed to do that. I specifically added these 3 lines to `/etc/portage/make.conf`
