Does nohup work across a pipe?
提问by Jasmine Lognnes
If I do
如果我做
nohup cmd1 | cmd2 &
is that the same as
是不是一样
nohup "cmd1 | cmd2" &
?
?
I would like that I nohupeverything, as cmd1will listen on port 8023.
我希望我的nohup一切，因为cmd1将在端口 8023 上侦听。

No, you need to add the nohup to the commands separately.
不，您需要单独将 nohup 添加到命令中。
Something like this is recommended:
推荐这样的东西：
nohup sh -c "cmd1 | cmd2" &
Or alternatively:
或者：
nohup $SHELL <<EOF &
cmd1 | cmd2
EOF

As an alternative to nohup, I recommend
作为替代nohup，我推荐
( cmd1 | cmd2 ) > logfile < /dev/null 2>&1 &
By rerouting stdin, stdout, and sterr from the terminal, this achieves much the same effect as nohup with a syntax that I, at least, prefer.
通过从终端重新路由 stdin、stdout 和 sterr，这使用至少我更喜欢的语法实现了与 nohup 几乎相同的效果。

You could start your pipe in a screensession. Keystroke Ctrl-aand then dwill detach the screen session from your terminal. You can then safely exit your terminal; the pipe will continue to run. Use screen -rto reconnect to the session again.
您可以在screen会话中启动管道。击键Ctrl-a，然后d将屏幕会话与您的终端分离。然后您可以安全地退出终端；管道将继续运行。用于screen -r再次重新连接到会话。

nohup cmd1 | cmd2 &
No, I have checked just now this is the as follows
不，我刚才查了一下，是这样的
nohup: ignoring input and redirecting stderr to stdout
