Git pull

git pull & git pull origin master

• git pull = git fetch + git merge

• git pull --rebase = git fetch + git rebase

• git pull <repo> <branch>:
  1st argument by default is the current branch’s remote.
  2nd argument by default is the current branch’s merge.

Say you are working on a local branch dev, whose upstream branch is origin/dev.

$ git branch -vv
* dev       328c854 [origin/dev] Chapter_5 outline
master    7dedf87 [origin/master] May 9 discussion (#14)

$ git config --get branch.dev.remote
origin
$ git config --get branch.dev.merge
refs/heads/dev

git pull will pull from origin/dev and merge to current dev branch.
git pull origin master can pull origin/master and merge to current dev branch.[!!]

Example:

You are developing on local dev branch, push to the origin/dev at times for a pr. Now the master has some new updates and you would like to sync with master. You can use git pull origin master to pull master’s new update and merge to your branch.

$ git pull origin master
Merge branch 'master' of github.com:arthma/iot-book into dev

Merge Two GitHub Repo

Say you have two github repo A and B. A is a copy of B and develop some features. Now you want to merge A back to B so the new feature can be added to B.

Go to B’s repo, git pull A’s code.

# In B repo. Pull A code
git pull git@github.com:A-organization/A-project-name.git

Then solve conflicts, submmit commit, git push, done.
