如何将多个变量从AppleScript传递到Shell脚本? [英] How to pass several variables from AppleScript to Shell script?

问题描述

我使用Automator执行以下操作:

I use Automator to do the following:

1. 要求用户选择一个文件夹(作为服务"操作)
2. 要求用户从列表中选择名称(AppleScript 从列表中选择... )
3. 将所选文件夹和所选名称传递给shell脚本

我了解如何将在步骤1中选择的文件夹传递给步骤2，但是我不明白如何在步骤2和3之间传递两个变量(我只能传递一个).我在步骤2中尝试返回{answer，input} .但是shell脚本失败，并出现错误-[__ NSArrayM fileSystemRepresentation]:无法识别的选择器发送到实例0x600000654b80 .

I understand how to pass folder chosen from step 1 to step 2. But I don't understand how to pass both variables between steps 2 and 3 (I can pass just one). I tried to return {answer, input} at step 2. But shell-script fails with the error -[__NSArrayM fileSystemRepresentation]: unrecognized selector sent to instance 0x600000654b80.

推荐答案

例如将参数列表传递给shell脚本操作时

When passing the list of parameters to a shell script action for example

return {"/Applications", "com.apple.application-bundle"}

• $ @ 表示由空格连接的扁平化列表-​​> "/Applications com.apple.application-bundle"
• $ 1 代表第一个参数-> "/Applications"

• $ 2 代表第二个参数-> "com.apple.application-bundle"

  • $@ represents the flattened list joined by spaces -> "/Applications com.apple.application-bundle"
  • $1 represents the first parameter -> "/Applications"

  • $2 represents the second parameter -> "com.apple.application-bundle"

    以此类推...

    shell脚本看起来像

    The shell script can look like

    mdfind -onlyin $1 "kMDItemContentType == $2"
    

    注意:确保在外壳程序脚本操作中将参数作为参数传递给 而不是传递给标准输入.

    Note: Make sure that the parameters are passed as arguments rather than to stdin in the shell script action.
