I need some help - less on Nethserver - however related to commands / bash:
I set of some long running copy processes using “&” to bring the processes to the background. I also used disown to release the process from the shell. Now I got some exit code [1]. Is there any command / option to look which exit code / error message was generated? I noted the PIDs, however I did not redirect the standard output to a file (e.g. >error_messages.txt).
Some of the jobs are already closed and the shell itself is also closed (while some of the processes are still running).
Instead of pushing tasks into the background using “&”, take a look at screen. It will allow you to run in a shell, then disconnect it to continue running with no terminal attached and then reconnect later to continue.
when you have to launch a command on a remote server that needs more than 2 seconds, please use screen
When the terminal is closed by a network issue, the process is stopped, during a yum update, you can break a lot of thing . With screen if the connection is lost, you can still come back inside the terminal.
I reckon you have other software that could do it .
