获取AppleScript中文件的最后修改日期

Question

我正在尝试获取AppleScript中文件的最后修改日期。我以为我使用以下方法工作：

set thePath to (((path to documents folder) as text) & "speed.txt")
set modDate to modification date of file thePath

这似乎返回了一个有效值，但是当我将其放入on idle一段代码中时，我得到了：

“无法获得...的类<>”错误

我在其他地方看到了使用建议：

set the modDate to (do shell script "mdls -name kMDItemLasUsedDate " & quoted form of the POSIX path of thePath)

但这又回来了null。关于如何获取修改日期的任何想法？

Answer 1

您需要引用该文件。

尝试

set thePath to (((path to documents folder) as text) & "speed.txt")
tell application "System Events" to set modDate to modification date of file thePath

要么

tell application "System Events" to set thePath to file (((path to documents folder) as text) & "speed.txt")
set modDate to modification date of thePath
