What is the difference between emerge world and emerge -u world? (Just Curious)

-u sets the update flag, which means, any package that does not come in newer version than the one installed, won't be emerged.

Then what would emerge world do? Does it emerge everything in the world file/directory? The list I get with emerge -p world is long but I do not believe it to be everything in the world file.

emerge world basically does a emerge `cat /var/lib/portage/world`.

It emerges any package that is in the world file.

the world file only contains packages that you have emerge by name (i.e if you do "emerge kde", the you will find kde-base/kde in the world file, but no nescessary all dependencies)

I think what you really wanted to know, is how to update the entire world: emerge -Du world.

To emerge everything " emerge world -e " though with portage-2.2 it will be the same as {emerge world -e} minus {emerge system -e}. To see how many files are in your world
