如何在 Mac 上运行 shell 命令？

Question

How could I run a shell command using Excel VBA code?

I want to run chmod +x /Users/asdasd/Music/playlistLoad.sh through the shell.

I achieved this using Python and os.system("Command here") .

Answer 1

The Shell command appears to be broken in the later versions of Excel on Mac. I couldn't get Shell to work at all on Excel v15.58 and I believe its due to sandbox issues.

The solution I found was to create a wrapper function in AppleScript that can be called from VBA and then executes the shell command and returns the result.

The extra hurdle (on top of creating the AppleScript) is that this script must be located in:

~/Library/Application Scripts/com.microsoft.Excel

Here is my wrapper script (saved as ShellExScript.scpt):

on ShellEx(shellCmd)
    do shell script shellCmd
end ShellEx

You can then execute shell commands from within excel like so:

Dim commandResult As String
Dim commandToRun As String

commandToRun = "ls ~/"

commandResult = AppleScriptTask("ShellExScript.scpt","ShellEx",commandToRun)

Range("A1").Value = commandResult

Answer 2

You will need to call the shell function. So your code would be

Shell("chmod +x /Users/asdasd/Music/playlistLoad.sh")

The shell function will work on any OS, however you need to adapt the command you pass to it to the OS you are working on. In your exemple, you have the UNIX style, so it will work only on Linux/MacOs or other *NIX systems. Windows don't have the notion of executable in it's permissions so there is no equivalent for your command in Windows anyway.
