Sure. I'm not a fan of 'NEXT' either. I would use INDEX. Or even index if that doesn't clash with anything. WTREE as well is not optimal but it is something you can get at as soon as you remember the term 'working tree'. And you know what you will get without consulting the manuals if you are unsure. >> Now I'll add a question I would want to ask: >> "I want to see the changes between what I have in my working tree and >> what I already added to the index" > > That's not a beginner question. Ok, I had a different definition of beginner, especially since I and all the git-user I know at my work place used the index from the beginning. The index is a wonderful idea but it isn't that hard to understand. If you look at the gittutorial man page (and any of the other 3 top tutorials in google) 3 of those 4 tutorials talk about the index and git add, only one uses 'git commit -a' instead. Only one mentions 'git diff --cached' by the way, seems to be an advanced topic ;-) >> git diff WTREE INDEX > ^^^^^^^^^^^ --- reverse to "git diff" > > In this direction it is surely suprising... you see, how again and again > having to explicitely state what to compare with which leads to mistakes > such like this one, and the one in few mails earlier. I'm a sloopy person as you have noticed. Also very forgetful. I usually don't bother with the order of 'diff' parameters when I can get the direction from the diff output. >> >> Btw. even the 'git diff' man page emphasizes that diff is about a >> comparision between two things.

Besides using your description it is also talking about comparision between working area and staging area and comparing staged changes to last commit. > Well, that depends by what you mean by beginner.

Learning git is not a role playing game where you have to master level 1 before you can use all the tricks of level 2 ;-). But any which way we call them there are a lot of users using git with index and all, but who have to search in the docs whenever they want to do something like unadding something from the index. Small things like 'git unadd', Jeff Kings 'git put' and git diff with targets probably would help this casual/intermediate/advanced user (take your pick).
