My git tips...

Ok, so a handy meme is loose: Handy Git tips. We even had a crazy anatidae requesting us to post this to the Git wiki whatever we send on this regard to our personal blogs.
Following Damog's post, I will also put my .bashrc snippet:

parse_git_branch() {
    branch=`git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
    if [ ! -z "$branch" ]
    then
	if ! git status|grep 'nothing to commit .working directory clean' 2>&1 > /dev/null
	then
	    branch="${branch}*"
	    mod=`git ls-files -m --exclude-standard|wc -l`
	    new=`git ls-files -o --exclude-standard|wc -l`
	    del=`git ls-files -d --exclude-standard|wc -l`
	    if [ $mod != 0 ]; then branch="${branch}${mod}M"; fi
	    if [ $new != 0 ]; then branch="${branch}${new}N"; fi
	    if [ $del != 0 ]; then branch="${branch}${del}D"; fi
 
	fi
    fi
    echo $branch
} 

This gives me the following information on my shell prompt:

• The git branch where we are standing
• If it has any uncommitted changes, a * is displayed next to it
• If there are changes not checked in to the index, M (modified), N (new) or D (deleted) is displayed, together with the number of files in said condition. i.e.,
  
  Sometimes, entering a very large git tree takes a second or two... But once it has run once, it goes on quite smoothly.
  Of course, I still have this also in .bashrc - but its funcionality pales in comparison:

  get_svn_revision() {
      if [ -d .svn ]
      then
  	svn info | grep ^Revision | cut -f 2 -d ' ' 
      fi
  }

  I am sure it can be expanded, of course - but why? :)
