Bash 应用程序总是给出-1708

我正在做一个基本的ping测试，以扩展我对bash和Applescript的知识，因此我做了以下测试：

on run argv
try
    if (count argv) is less than 1 or (count argv) is greater than 1 then
        set IP_address to ""
        set dialog_1 to display dialog "Enter IP Address:" default answer "" with title "Ping"
        set the IP_address to the text returned of dialog_1
        try
            set ping to (do shell script "ping -c 2 " & IP_address)
            display dialog "Connection Successful." buttons {"OK"} default button 1
            return 1
        on error
            --if we get here, the ping failed
            display dialog "Conection failed. Host is down" buttons {"Darn"} default button 1
            return 0
        end try
    end if
    if (count argv) = 1 then
        set IP_address to item 1 of argv
        try
            set ping to (do shell script "ping -c 2 " & IP_address)
            return 1
        on error
            -- if we get here, the ping failed
            return 0
        end try
    end if
on error error_message number error_number
    if (error_number) is not equal to -128 then
        display alert ("An error has occured!") message error_message & (" Error number ") & error_number & "."
    end if

    return error_number
end try

终点

（我无法在代码段中获得结束运行）

在bash中，我做了这样一件事：

on run argv
try
    if (count argv) is less than 1 or (count argv) is greater than 1 then
        set IP_address to ""
        set dialog_1 to display dialog "Enter IP Address:" default answer "" with title "Ping"
        set the IP_address to the text returned of dialog_1
        try
            set ping to (do shell script "ping -c 2 " & IP_address)
            display dialog "Connection Successful." buttons {"OK"} default button 1
            return 1
        on error
            --if we get here, the ping failed
            display dialog "Conection failed. Host is down" buttons {"Darn"} default button 1
            return 0
        end try
    end if
    if (count argv) = 1 then
        set IP_address to item 1 of argv
        try
            set ping to (do shell script "ping -c 2 " & IP_address)
            return 1
        on error
            -- if we get here, the ping failed
            return 0
        end try
    end if
on error error_message number error_number
    if (error_number) is not equal to -128 then
        display alert ("An error has occured!") message error_message & (" Error number ") & error_number & "."
    end if

    return error_number
end try

!/bin/bash currentDir=

pwd

Success=

$currentDir/$1/Contents/MacOS/applet$2

回声$成功

（我无法在代码片段中获得这些信息）

当我只运行AppleScript时，在编辑器中它工作正常，但是.app和bash版本给了我-1708错误。我已将问题缩小到以下范围：

如果（count argv）小于1或（count argv）大于1，则

我能做些什么来修复这个问题，或者干脆让我的代码更整洁

谢谢

编辑（1）：如果没有提供任何参数，我希望我的程序运行GUI版本，并且当传递参数时，我希望它在后台运行。

您可以直接从bash向AppleScript传递参数，如下所示：

--AppleScript named myScript.scpt
    on run {argv}
        beep argv
    end run 

命令：

osascript -e 'run script "/Users/user1781742/Desktop/myScipt.scpt" with parameters {2}'

谢谢，但是如果没有提供任何参数，我希望我的程序运行GUI版本，当传递参数时，我希望它在后台运行。（将添加到OP）
