Liquibase vs Flyway

• 面對不同版本之間的 Database Schema 異動，需要一些管理工具，目前聽到兩套，一套是 Liquibase 另一套是 Flyway
• 先來看一下兩套的差異比較

Mac OS

• cron job 寫法還是跟 linux 一樣

  ~$ crontab -l
  0 14 * * * osascript -e 'display notification "checking traffic routes" with title "Check Google Maps"'
  0 18 * * * osascript -e 'display notification "checking traffic routes" with title "Check Google Maps"'
  

• Mac OS 的 notify-send 指令有點不一樣，要靠 osascript 執行 AppleScript
