Hello,

I learned that nohup command can run a command after closing the session from this article https://likegeeks.com/linux-command-line-tricks/.
Now, what about returning back and see the progress of the running command?
How can I return to see the results?

Thank you.

nohup

will automatically output the data to a file named nohup.out which is located in the working directory (the directory location which you executed the command line). You've to use a text editor to look up at that file.

Alternatively, you can tell nohup to redirect the output to a defined file. To do so you must use the following command line below.

nohup some_command > output.log 2>&1&

output.log is only an example, you can replace the filename with whatever you want.

Thanks for the reply.
Do you mean that I can use tail -f to see the live results of the command?

If you can, use

screen

. The program keeps your application alive even when you log out or lose the SSH connection.

screen -S my_awesome_cs2d_server ./cs2d_dedicated

Ctrl + C

to shutdown the program

Ctrl + A > D

to detach from the session (program stays alive)

To reconnect to your program, run:

screen -x my_awesome_cs2d_server

If the program crashes, the screen session will close too. To see which screen sessions are still active:

screen -ls

If you forgot to give it a name, you can connect via the process id seen in the

screen -ls

list, e.g.:

screen -x 1573
