问题描述
我在终端中使用 open cairo-dock 打开了 Cairo-dock，这有效，但如果我关闭终端，它也会随之消失。无论终端如何，如何保持它打开？
最佳答案
\\n
nohupis a POSIX command to ignore the HUP (hangup) signal. The HUP (hangup) signal is by convention the way a terminal warns depending processes of logout.\\n Output that would normally go to the terminal goes to a file called nohup.out if it has not already been redirected.\\n nohup is a low-level utility simply configuring a command to ignore a signal. As seen below, nohup is very far from being a full-featured batch system solving all the problems of running programs asynchronously.\\n
参见手册：
man nohup
例子：
nohup cairo-dock &

另一种方式：disown
In the bash shell, the disown builtin command is used to remove jobs from the job table, or to mark jobs so that a SIGHUP signal is not sent to them if the parent shell receives it (e.g. if the user logs out).
例如：
cairo-dock & disown
第三种答案
我个人使用屏幕来处理这类事情。
screen -d -m -S cairo_session open cairo-dock
这样做的好处是，如果您想终止 cairo-dock，您可以重新连接到屏幕会话并终止它。
screen -S cairo_session -X quit
Screen还有其他用途。它是一个终端多路复用器。
