Question

我编写了这个简单的脚本，用于更改桌面上文件夹Images的文件名。该脚本在第一次运行时工作，但是当我使用不同的字符串为变量newName重新运行它时（相同的字符串会抛出错误：filename已经存在）。它只更改文件夹＆＃34;的＆＃34;项目x的偶数名称。有人可以告诉我这是如何发生的，以及如何避免这种奇特的行为。我很难搞清楚这一点。非常感谢你提前。

tell application "Finder"
    set theFolder to ((path to desktop folder) & "Images") as string as alias
    set myImages to the name of every file of theFolder
    set indexOfFolder to (count items in myImages) as number
    set newName to "whateverName" as string

    repeat with x from 1 to indexOfFolder
        set name of item x of theFolder to newName & x & ".JPG"
    end repeat
end tell

编辑：经过一些更多测试后，问题似乎并不仅仅指向未改变的不均匀数字。有超过20个文件，它似乎从20开始切换到不会重命名的偶数。

在我看来，你正在处理文件夹的名称，以及文件夹的字符（文件夹的项目）

请与此比较，以便正常工作：

 tell application "Finder"
    set theFolder to ((path to desktop folder as text) & "Images")
    set myImages to the name of every file of folder theFolder
    set indexOfFolder to (count myImages)

    set newname to "Z picture " as string

    repeat with x from 1 to indexOfFolder
        set name of item x of folder theFolder to newname & x & ".JPG"
    end repeat
 end tell

它仍然没有错误，下一个差异是您在将内容收集到myImages变量时使用文件，但是您解决了文件夹的项目，这是两个不同的对象类。我还最后将文件夹设置为最后一个实现，以避免冗余。请求还要注意我放置强制的地方，以及我已经删除的强制措施，因为它们是多余的。

 tell application "Finder"
    set theFolder to folder ((path to desktop folder as text) & "Images")
    set myImages to the name of every file of theFolder
    set indexOfFolder to (count myImages)

    set newname to "Z picture " as string

    repeat with x from 1 to indexOfFolder
        set name of file x of theFolder to newname & x & ".JPG"
    end repeat
 end tell

即使文件更改名称，此版本也应该可以正常工作，因为文件列表是预先获得的。

tell application "Finder"
    set theFolder to folder ((path to desktop folder as text) & "Images")
    set myImages to every file of theFolder
    set indexOfFolder to (count myImages)

    set newname to "Z picture " as string

    repeat with x from 1 to indexOfFolder
        set name of item x of myImages to newname & x & ".JPG"
    end repeat
  end tell
