Jenkins job to manage jenkins configs

jenkins-auto-git.sh

# Move into the jenkins directory
cd /var/lib/jenkins

#Add all top level xml files.
git add *.xml

# Add all job config.xml files.
git add jobs/*/config.xml

# Add all user config.xml files.
git add users/*/config.xml

# Add all user content files.
git add userContent/*

# Remove files from the remote repo that have been removed locally.
COUNT=`git log --pretty=format: --name-only --diff-filter=B | wc -l`
if [ $COUNT -ne 0 ]
  then git log --pretty=format: --name-only --diff-filter=B | xargs git rm
fi

# Commit the differences
git commit -a -m "Automated commit of jenkins chaos"

# Push the commit up to the remote repository.
git push origin master

Should it really be git log ... --diff-filter=B ?
I get a list of the deleted files when I do git diff ... --diff-filter=D.
