GIT notes by Simon PJ

Here are notes about using Git that Simon PJ has found useful.


Push only the current branch

When you say git push (with no arguments), push only only patches on the current branch. If you have un-pushed commits on other branches, leave them be.

git config --global remote.origin.push HEAD

Creating tracking branches

Suppose you create a new branch on your local machine. Now you want to push it up to the global repo. You almost certainly want your local branch to become a tracking option of the remote one, so that git pull will merge changes to the remote copy into your local copy.

git config --global branch.autosetupmerge true

Looking at the current state of affairs

Show a one-line-per-file summary of diffs between working files and the local repo:

git diff --stat

Show the commits that are on branch my-test but not on the main trunk:

git log `git merge-base master my-test`

The git merge-base b1 b2 thing returns the name of the commit that is the common ancestor of branches b1 and b2.

Doing useful things

You are sitting on a branch (say master), and do some edits. Now you decide it wasn't as simple as you thought so you want to create a branch to keep your edits safe while you do something else.

git checkout -b <new-branch-name>

This creates the new branch and switches to it, but does not change your working files. Now you can safely commit on the branch. Stackoverflow link

git gui on Windows

I’ve been using git gui (on Windows at least) as a way to examine and stage changes. But I suddenly found that it wasn’t displaying the diff in the main pane.

A google search suggested that (bizarrely) it might have something to do with ‘nice’.

So I renamed c:/cygwin/bin/nice.exe to c:/cygwin/bin/cygin-nice.exe, and that made git gui worked fine. Wierd.
