Make 'rm' move files to the trash instead

Put this at your ~/.bash_profile

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
}
