我想在 ubuntu 台式计算机上开始一个大型模拟。我可以物理（非远程）访问这台 PC。此模拟可能需要数周时间。启动进程的命令是：

mpirun -np 100 icoFoam -parallel | tee log

icoFoam可执行文件在哪里，-parallel需要作为它的选项。
此命令在终端中打印数据。有时终端关闭或操作系统在长时间模拟期间随机注销，因此，进程终止。我试图通过几个替代命令来解决这个问题：

nohup mpirun -np 100 icoFoam -parallel > log  & 
nohup mpirun -np 100 icoFoam -parallel > log  & disown & 
nohup mpirun -np 100 icoFoam -parallel | tee log & disown & 
nohup mpirun -np 100 icoFoam -parallel | tee log & disown & > /dev/null 2>& 1 & nohup mpirun -np 100 icoFoam -parallel > /dev/null 2>& 1  &
systemd-run --scope --user mpirun -np 100 icoFoam -parallel | tee log &
systemd-run --scope --user mpirun -np 100 icoFoam -parallel | tee log & disown &
systemd-run --scope --user nohup mpirun -np 100 icoFoam -parallel | tee log & disown &
tmux

结果
除了 form tmux，使用这些命令中的任何一个，当我关闭终端时，进程都会终止。
tmux当我从我的用户帐户注销时也会终止。

我的发现

  1. 作为最简单的解决方法，我混合了nohup和disown（从这里）。
  2. 我猜想包括 , 在内的命令由于关闭终端（从这里）而tee被终止。因此，我使用重定向到日志文件或（从这里），这两者也都通过关闭终端而终止。 SIGPIPE/dev/null
  3. 我也检查了systemd-run。但它也可以通过关闭终端来终止。

  4. 为了查看程序是否安装了自己的处理程序，我执行了这个：

    nohup mpirun -np 100 icoFoam -parallel > log  &
grep Sig /proc/$!/status

    哪个返回

    SigIgn: 0000000000000000

    因此，我猜是这种情况，即mpirun安装了自己的处理程序来覆盖nohup（从这里）的保护。

  5. 我不知道是否可以发送自定义处理程序以mpirun不覆盖nohup.

我的问题
我想执行以下命令，以便只要终端未关闭，它就会在终端中打印输出，并且不会通过关闭终端或从用户帐户注销来终止该过程。

mpirun -np 100 icoFoam -parallel

操作系统：Ubuntu 18.04
可执行文件：OpenFOAM
mpirun（Open MPI）：2.1.1

更新
通过注销，我的意思是按注销按钮（图像），而不是锁定屏幕（super+L） 在此处输入图像描述

先感谢您。

最近，我的freecad遇到了一个奇怪的透明问题。当我打开它时，没有问题（图片）。但是当我选择去一个特定的工作场所时，比如说part，窗口变得透明，所以我的桌面在 freecad 背面可见（这是我的桌面，这是 freecad 窗口）。
我已删除并重新安装它，但问题仍然存在。我还必须提到，这不是不透明的问题，可以通过以下方式从终端控制：sh -c 'xprop...
