Git Commit Hooks for auto deploying

  #!/bin/bash
  vim - "+VimwikiIndex" "+VimwikiAll2HTML" "+quit"
  ~/vimwiki/site_html/sync.sh

  # also, if you want to just send normal commands
  # the following would move you into the second wiki
  vim - "+normal 2\ww" "+VimwikiAll2HTML" "+quit"

If you happen to want to run vim in a git commit hook, like I do for this wiki

  git update-index --skip-worktree FILENAME

ignore a file locally which has been checked into git (useful for database.yml for example)

  git ls-files -v | grep '^S'

Show the locally ignored (skipped) files (i.e. to find what you did above)

Copy untracked files into a different directory

  git ls-files --others --exclude-standard -z | cpio -pmd0 ../untracked-backup/

Zip up files which have changed between current branch and master

  git diff master --name-only | zip -@ changed.zip

List tags and their annotated messages git tag -l -n1

Order branches by latest commit git for-each-ref --count=30 --sort=-committerdate refs/heads/ --format='%(refname:short)'

Delete branches merged into current branch. Won't delete master or current branch. git branch --merged | grep -v "\*\|master" | xargs -n 1 git branch -d

Excellent introduction to reset

Nice way to revert a whole lot of commits in one go

# from the above stack overflow article

# reset the index back to the state you're interested in.
git reset <sha>

# reset the branch pointer back to previous HEAD .
git reset --soft HEAD@{1}

# commit your changes
git commit -m "my happy state"

# update working copy to reflect the current commit
git reset --hard
# run rake for all versions of [master](master)
git rev-list --reverse master | while read rev; do git checkout $rev; git clean -df; rake; done; git checkout master

# see lines of code changed between branch and master, excluding spec directory
git diff master --stat -- . ':(exclude)spec'
