Git pull-在osx / linux上的行为各不相同

Question

I thought running git pull --all was pulling the contents of all remote branches to the local repository. Until this morning anyway, when I ran this on my MacBook:

[me@macbox folder]> git --version
git version 1.9.3 (Apple Git-50)
[me@macbox folder]> git branch
* foo
  master
[me@macbox folder]> git remote -v
origin  git@gitserver:me/myrepo.git (fetch)
origin  git@gitserver:me/myrepo.git (push)
[me@macbox folder]> git pull --all
Fetching origin
You asked to pull from the remote '--all', but did not specify
a branch. Because this is not the default configured remote
for your current branch, you must specify a branch on the command line.
[me@macbox folder]> git checkout master
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
[me@macbox folder]> git pull --all
Fetching origin
Already up-to-date.

I don't understand that error, isn't the whole point of specifying --all not to have to specify a branch? What is even more upsetting, is that the same code seem to work just fine on my Linux box:

[me@linuxbox folder]> git --version
git version 1.7.1
[me@linuxbox folder]> git branch
* master
[me@linuxbox folder]> git remote -v
origin  git@gitserver:me/myrepo.git (fetch)
origin  git@gitserver:me/myrepo.git (push)
[me@linuxbox folder]> git pull --all
Fetching origin

I understand that it might be too optimistic to hope for the same program to behave in the same way on different OSs, but I would like to know if I am doing this correctly, or whether this is a version problem, or whether I misunderstood something?

Answer 1

Sorry for my previous question, I think I figured out the answer. Apparently I didn't define the upstream for my local branch foo . Running the following made git pull --all run fine on osx:

git branch -u foo origin/foo

For reference, based on this answer , the following command is useful to check the current tracking state of your repo:

git remote show origin
