zshのプロンプト表示を定期更新

Zsh

More than 5 years have passed since last update.

プロンプト左側の表示を０〜９までカウントアップさせる例
任意のコマンドを実行できるため、天気や時計、脈拍数なんかを表示させたら面白いかもしれない。

setopt PROMPT_SUBST
COUNT=0
PS1='$COUNT $ '
# Handler for ALRM signal
TRAPALRM () { 
  if [ $COUNT -lt 10 ]; then
    COUNT=`expr $COUNT + 1`
  fi              
  zle reset-prompt # update PS1
}                 
TMOUT=1 # interval secound
