bash replacement for rm to prevent shooting yourself in the face.

gistfile1.sh

function rm () {
  local path
  for path in "$@"; do
    # ignore any arguments
    if [[ "$path" = -* ]]; then :
    else
      local dst=${path##*/}
      # append the time if necessary
      while [ -e ~/.Trash/"$dst" ]; do
        dst="$dst "$(date +%H-%M-%S)
      done
      mv "$path" ~/.Trash/"$dst"
    fi  
  done
}

From my .bashrc. Shamelessly stolen from the Internet.

If you're not removing something in your home dir, this is going to cause some very strange consequences. I would suggest that if you're taking the trouble to sudo rm something, you probably mean it.
