Git - Merge

About

Merge is a git merge tool that is designed to integrate changes from one branch into another branch

It joins two or more branch together (ie development histories)

The pull command is a wrapper that calls also the merge command.
rebase is also designed to integrate changes to get an easier commit log: See What is the difference between a merge and a rebase?

Imagine this commit history (log) with a remote and a local branch where the commit in the remote branch will be integrated into the local branch.

- A - B - C - D - remote HEAD
    \
      E - F - G - local HEAD

After a merge, the commit history (log) will look like:

- A - B - C - D - remote HEAD
    \                         \
      E - F - G - local HEAD - new local HEAD
