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 one-line-per-file diff summary
Show a one-line-per-file summary of diffs between working files and the local repo:
git diff --stat
Show delta between branch and trunk
Show the commits that are on branch my-test but not on the main trunk:
git log `git merge-base master my-test`..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
Create a branch after doing some edits
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
Work on a branch gotten from the main repo
You have done a git fetch to get the upstream repo, which has a branch origin/experiment. You want a local experiment branch which tracks origin/experiment:
git branch --track experiment origin/experiment
Now you can git checkout experiment to move onto your local experiment branch.
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 http://code.google.com/p/msysgit/issues/detail?id=394 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.
