AppleScript的，以检查是否存在的文件 [英] Applescript to check if files exist

问题描述

我要检查是否有任何特定的文件（字典）中的/资源库/词典/存在。这里是我的AppleScript code线：

I want to check if any of particular files (dictionaries) exist in "/Library/Dictionaries/". Here is my Applescript code lines:

tell application "Finder"
try
    set theFolder to ("/Library/Dictionaries/")
    set fileNames to {"dict1.dictionary", "dict2.dictionary", "dict3.dictionary", "dict_n.dictionary"}
on error
    set fileNames to false
end try
if fileNames is not false then
    try
        display dialog "You have already got the dictionary."
    end try
end if
end tell

古怪，消息您已经得到了词典。总是尽管没有公开的文件显示存在。

Weirdly, the message You have already got the dictionary. is always shown albeit no listed files exist.

我的目的是检查是否有任何列出的文件出口的，如果一个或更多的人退出则消息是要显示。

My purpose is to check if any of the listed files exits, and if one or more of them exits then the message is to be displayed.

事实上，该脚本将通过的/ usr / bin中/ osascript 运行在Unix bash脚本，所以我会很感激，如果你可与苹果帮助脚本或Bash脚本。

In fact, this script will be run as a Unix bash script via /usr/bin/osascript, so I will be very grateful if you can help with either Apple script or Bash script.

推荐答案

尝试

   set theFolder to (path to library folder as text) & "Dictionaries:"
set fileNames to {"Apple Dictionary.dictionary", "dict2.dictionary", "dict3.dictionary", "dict_n.dictionary"}

set dict to {}
repeat with aFile in fileNames
    tell application "Finder"
        if exists file (theFolder & aFile as text) then set end of dict to aFile & return
    end tell
end repeat

if dict ≠ {} then display dialog "You have the following dictionaries installed:" & return & dict
