Answer 1

此脚本按照您的要求执行操作，您使用osascript从cmd行运行它。

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

由Bavarious编辑：为了在shell脚本中使用Adam的AppleScript，您可以执行以下操作：

#!/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}")

cnt=$(w -h | grep "^$(whoami) *s[^ ]* *-"|wc -l)
echo Your current terminal sessions: $cnt
