Bash -使用对话框确认卸载应用程序

Question

我有一个用Applescript来显示对话框外观的例子，但是我想不出如何在Bash文件中这样做。

巴什：

#!/bin/bash
app="/Applications/Cisco Spark.app"
FileToDelete=$app
if [ -d "$app" ];  # Remove, if exists.
then
echo ""$FileToDelete""
rm -r "$FileToDelete" #Removing App 
else
echo $app
fi

Applescript：

display dialog "Webex Teams is replacing Cisco Spark! This installation will close and uninstall Cisco Spark." buttons {"Cancel Installation", "Install Teams"} default button "Install Teams"


if result = {button returned:"Install Teams"} then
    tell application "Cisco Spark"
        quit
    end tell
end if

Answer 1

这就是我想出的解决办法。效果很好！谢谢你的帮助！

#!/bin/bash
response=$(osascript -e 'button returned of (display dialog "Webex Teams is replacing Cisco Spark!\n" & "The full installation will close and uninstall Cisco Spark." buttons {"Cancel Spark Removal", "Remove Spark"} default button "Remove Spark")')

    # Exit script if user cancels
    [[ "$response" = "Cancel Spark Removal" ]] && exit 0

    #If not cancelled, delete application
    FileToDelete="/Applications/Cisco Spark.app"
    if [ -d "$FileToDelete" ];  # Remove, if exists.
    then
    echo "Closing Cisco Spark"
    killall "Cisco Spark" || echo "Spark wasn't open"
    echo "removing Cisco Spark.app"
    rm -r "$FileToDelete"
    else
    echo "Cisco Spark is not installed on this device"
    fi

下面是您的bash脚本的修改版本，其中包括允许用户取消或继续的对话框弹出，如您的AppleScript中所示：

    #!/bin/bash
    response=$(osascript -e 'button returned of ¬
              (display dialog "Webex Teams is replacing Cisco Spark!\n" & ¬
              "This installation will close and uninstall Cisco Spark." ¬
              buttons {"Cancel Installation", "Install Teams"} ¬
              default button "Install Teams")')

    # Exit script if user cancels
    [[ "$response" = "Cancel Installation" ]] && exit 1

    # Get PID of "Cisco Spark" application
    pid=$(lsappinfo info -only pid "Cisco Spark" | egrep -o '\d+')
    # If running, quit the application
    [[ -z "$pid" ]] || kill -QUIT $pid

    # Delete the application file
    app="/Applications/Cisco Spark.app"
    rm -R "$app" 2>/dev/null && echo "Done." || echo "$app not found."

在最后一行中，我将stderr重定向到/dev/null，以便在应用程序文件不存在时保持沉默。这只是另一种方法，而不是在选择删除文件之前先检查文件是否存在。
