This function gets pretty close to must-have parts of 

watch() {
  local i=${1:-2}; shift
  while :; do
    tput cup 0 0
    printf "\033[1mEvery %ss — %s\033[0m\n\n" "$i" "$(date)"
    "$@" 2>&1
    sleep "$i" || break
  done
}

Do you have any shell functions/aliases that you find useful?

I found myself wanting `watch` on macos, and [was taught it's a linux specific thing](https://stacker.news/items/1402280/r/k00b?commentId=1402620).
