Having a standard way to manage .gitignore files

LC_ALL=C sort .gitignore | uniq | grep -Ev "^$" >.gitignore.tmp ; mv -f .gitignore.tmp .gitignore ; echo ''>>.gitignore

You can add following code to you ~/.bashrc

function gitignore_standard {
  if [ -f '.gitignore' ] ; then
    LC_ALL=C sort .gitignore | uniq | grep -Ev "^$" >.gitignore.tmp ; mv -f .gitignore.tmp .gitignore ; echo ''>>.gitignore
  else
    echo "*** Not file .gitignore in current folder." >&2
  fi
}
