print_in_top_right () {
  local columns=$(tput cols)           # get the terminal width
  local text=${1:0:$columns}           # truncate the text to fit on a line if needed
  tput sc                              # Save the Cursor position
  tput cup 0 $((columns - ${#text}))   # move the CUrsor Position to the top line, with just enough space for $text on the right
  printf %s "$text"
