Is git fetch notification only? -

i learning git through the book , git help command.

i changed content of origin , commited it. launched git fetch origin command in "local copy" of repository.

$ git fetch origin remote: counting objects: 4, done. remote: compressing objects: 100% (3/3), done. remote: total 4 (delta 0), reused 0 (delta 0) unpacking objects: 100% (4/4), done. d:/_git.sandbox/./my_remote_project    a03e9df..837c57d  master     -> origin/master 

this info not clear me... book:

as saw, data remote projects, can run:
$ git fetch [remote-name]
command goes out remote project , pulls down data remote project don’t have yet. after this, should have references branches remote, can merge in or inspect @ time.

if after git fetch origin origin unavailable error git pull. so, in opinion, git pull requeries available origin , uses still instead of downloaded remote repository's changes. i.e. git fetch tells me origin repository changed (if occurred), doesn't download these changes local repository. download these changes , implement in local version of repository execute git pull. i.e. git fetch method of informing up-dating of repository of 'origin' when launch 'git status'? right?

no.

git fetch downloads remote repository's changes don't have stored locally. not apply them local branches though.

git pull git fetch followed git merge of branches have set merge when pulling.
