memo：macOS通过命令获取文件时间

今天测试了下从终端获取本地文件的修改时间，顺便记录一下。

• atime The time file was last accessed

    date -r $(stat -f "%a" $FILE) +"%FT%T%z"
  

• mtime The time file was last modified

    date -r $(stat -f "%m" $FILE) +"%FT%T%z"
  

• ctime The time inode was last changed

    date -r $(stat -f "%c" $FILE) +"%FT%T%z"
  

• create time The time inode was created

    date -r $(stat -f "%B" $FILE) +"%FT%T%z"
  

总结： stat 是个非常有用的命令。
