Change the remote for a repository:

git remote add origin git@github.com:rjwalls/REPO_NAME.git

#Or if origin exists already
# git remote set-url origin git@github.com:rjwalls/REPO_NAME.git

git push -u origin master

Make a copy of the repository files without any git information:

git archive master | tar -x -C /somewhere/else

Need to remove large files from your repo history? Check out bfg.

Checkout a particular commit-version of a file.

git checkout ASDFHDFS file.txt

Check the size of the repo.

git bundle create tmp.bundle --all
du -sh tmp.bundle

Get around the “Invalid certificate chain” error.

git config --global http.sslVerify false

Get the differences in the working version of a file.

git diff HEAD~1 file.tex

List the tracked files in the current directory.

git ls-files

Globally ignore all files named *.swp.

echo *.swp >> ~/.cvsignore
git config --global core.excludesfile '~/.cvsignore'

Remove *.swp files from a repository—assuming they are being tracked already.

git rm -cached *.swp 

Remove *.swp files from both current directory and repository.

git rm *.swp

Stash your local changes. This is useful when you need to go back to the original working state.

git stash save "the stash info"

Amend local commit; useful when you forgot to add some changes in the current commit.

# Used git ci -m "my commit" already
git commit -a --amend 

Export the repository without the .git information.

git archive master | tar -x -C /somewhere/else

Check out a file from any commit (commits are identified by SHA1 hash of 40 characters).

git checkout commit_sha1 filename

Drop all the local changes since last commit and push to remote harsh.

git fetch origin
git reset --hard origin/master

Git Svn

git svn clone https://address.of.repo.com

Gotcha: The svn directory needs to have at least one commit or you will get errors when you clone.

Git and Latex

Generate a diff PDF for the working directory. Make sure you have the git-latexdiff wrapper installed.

git latexdiff HEAD~1 --

#Or
git latexdiff HEAD~3 HEAD --main paper/paper.tex --whole-tree -c"PICTUREENV=(?:picture|DIFnomarkup|lstlisting|lstinline)[\w\d*@]*"

Github Pages

Github pages is an awesome thing, but sometimes you don’t actually need a master branch for your project. For example, the repository for this site. First thing you need to do is set gh-pages to be your default branch on Github. You can do this by going to “Settings>Branches” from the repository page on Github. Once there, just select gh-pages using the drop down.

Now on your local repo do the following:

git checkout gh-pages
git branch -D master
git push origin :master

I got this tip from here.
