rebasing using git gui

Q. How to do git pull --rebase using git gui?

A. The trick is to add a custom command in git gui:

 Tools -> Add
 Name: Pull with Rebase
 Command: git pull --rebase origin
 Add globally -> check
 Add

The new command will appear under Tools menu.

Generate diff with no context

git diff -U0

In general, to generate a diff with <n> lines of context, use

git diff -U<n>

or

git diff --unified=<n>

The default is 3 lines of context.

show modified files in the current directory only

    git status .
    

or more generally

    git status /path/to/dir
    

works from git 1.7 onwards. Does not work with git 1.6.

time zone of the committer

    git cat-file -p <commit-id>
    

Will show the entire commit object. It will contain two lines like this:

    author Foo Bar <foo@bar.com> 1398017575 -0400
    committer Foo Bar <foo@bar.com> 1398017575 -0400
    

As you can see, the timezone info follows the Unix-epoch timestamps.

Note that the timezone is something set by the user himself on the client. So it can be easily spoofed by the user if he desires to.

cache username and passwords

for HTTPS authentication

    git config --global credential.helper wincred
    

This works. But how is it different from

    git config --global credential.helper manager
    

?

number of commits

To get a commit count for a revision (HEAD, master, a commit hash):

    git rev-list --count <revision>
    

To get the commit count across all branches:

    git rev-list --count --all

Migrate from sourceforge to github

The instructions to move a git repository from sourceforge to github are clearly laid out in https://help.github.com/articles/importing-a-git-repository-using-the-command-line/ .

In particular, to migrate the sampleusage project from sourceforge to github, I did

Login into github website
create a new repository called sampleusage: https://github.com/KamarajuKusumanchi/sampleusage
git clone --bare ssh://kamaraju@git.code.sf.net/p/sampleusage/git sampleusage-git
cd sampleusage-git
git push --mirror https://github.com/KamarajuKusumanchi/sampleusage.git
cd ..
rm -rf sampleusage-git

To get a local copy

git clone git@github.com:KamarajuKusumanchi/sampleusage.git
cd sampleusage
git config user.name "KamarajuKusumanchi"
git config user.email "kamaraju@gmail.com"

Sample work flow once it is all done

git add dummy_file
git commit -m "dummy commit message"
git push -u origin master

After making sure that everything on github is working properly, I submitted a ticket to delete the original sourceforge project.
