如何获得最前面(或凸起或聚焦)终端窗口的tty
? (这是必需的,以便我可以确定脚本是在前台还是后台运行。)
答案 0 :(得分:1)
以下脚本返回最前面的终端窗口的tty
,如果所有这些窗口都被最小化/隐藏,则返回空字符串:
#!/usr/bin/env osascript
tell application "Terminal"
if frontmost is true
repeat with w in windows
if (frontmost of w) is true then
set t to (selected tab of w)
return (tty of t) as string
end if
end repeat
end if
end tell
用法:
$ frontmost-tty
/dev/ttys001
$ tty
/dev/ttys001
$ sleep 5 ; frontmost-tty # switch Terminals
/dev/ttys000
