由Bavarious编辑:要在外壳程序脚本中使用Adam的AppleScript，您可以执行以下操作:

Edit by Bavarious: In order to use Adam’s AppleScript inside a shell script, you can do the following:

#!/bin/bash
read -d '' OSASCRIPT << EOF
    tell application "Terminal"
        set c to 0
        repeat with i from 1 to (count of windows)
            set c to c + (count of tabs in window i)
        end repeat
        c
end tell
EOF

nwindows=$(osascript -e "${OSASCRIPT}")
