flinte Posted August 14, 2019 Share Posted August 14, 2019 I am new to unraid and evaluating it. I am transferring data from my old NAS to my new unraid box using rsync on the cli. When I attempt to push the command to the background with "nohup &" but when I log off and back on my rsync job has been terminated. Help me understand why this is.

itimpi Posted August 14, 2019 Share Posted August 14, 2019 No idea why your approach is not working, but one tried and tested method of achieving what you seem to want is to install the ‘screen’ pack via the Nerd Tools plugin and then start a ‘screen’ session from the CLI and run the command from there. 1 Quote Link to comment
flinte Posted August 14, 2019 Author Share Posted August 14, 2019 Thank you, that worked. Not sure why nohup didnt though. Quote Link to comment
Xaero Posted August 15, 2019 Share Posted August 15, 2019 The reason nohup doesn't work for this is because when you disconnect, or log out of that terminal, that terminal, and any child processes of the terminal are killed. This is just Linux kernel process management doing it's job. To prevent this you can just disown the process, no need to nohup it. For example you can: $ processname & $ disown and "processname" will continue running after the terminal is killed. This is good because it means that "processname" will still respond to hangup, which may be needed. Of course, you could also call disown with nohup: $ nohup processname $ disown You can also disown processes by using their PID, but calling it immediately following the spawn of a process will automatically disown the last created child. 1 Quote Link to comment
NewDisplayName Posted August 16, 2019 Share Posted August 16, 2019 (edited) anyway, just installing screen and using it, is much simpler for standard people btw just look at the nerd plugin there are many usefull things. like htop, nethogs... Edited August 16, 2019 by nuhll Quote Link to comment
