![]() The terminal, and a service unit would be terminated. rvice(5) unit, because screen will exit when detaching from A systemd.scope(5) unit is used instead of a The systemd -user process that was started by, in a This starts the screen process as a child of Blocked entries have a -> prefix before the lock type column (thus adding a column to that line). Since you know the file, that ought not be a problem. Start screen as a user service $ systemd-run -scope -user screen Running scope as unit lslocks reads /proc/locks, in a pinch you can read that directly yourself, with the caveat that files are identified by device and inode rather than name. See example in systemd-run(1).Īnd indeed looking at the manual for systemd-run(1) we find the following example: Example 5. Note that setting KillUserProcesses=yes will break tools like screen(1) and tmux(1), unless they are moved out of the session scope. The manual for nf(5) contains the clue to this one: See the description of enable-linger in loginctl(1). Depending on the linger settings, this may allow users to run processes independent of their login sessions. In addition to session processes, user process may run under the user manager unit. The clue can be found from the nf(5) manual page: You can enable lingering for the current session by executing loginctl(1) as follows within the session scope (obviously replace username for the actual user name or $(whoami)): loginctl enable-linger username You can see sessions with loginctl list-sessions. So one could set KillUserProcesses=no or only include user gdm in KillOnlyUsers (if using GNOME) or list the users to be exempt from process killing on login session teardown via KillExcludeUsers. KillExcludeUsers= is the opposite of the previous setting an makes users exempt from the effect of KillUserProcesses=yes.KillOnlyUsers= will allow to limit the list of users for which the above setting applies (space-separated list, e.g.KillUserProcesses= (if yes a logoff will cause processes within the scope of the rvice(8) session to be killed.etc/systemd/nf and friends contain three relevant settings: Several ways seem to exist to mitigate the issue: 1. The pointer with systemd by Nicholas was spot on. View all processes owned by you : Processes i.Meanwhile I have researched this further. You can view all the running processes, by using -r option : It’s time to print all processes associated with this terminal, So you can -T option to do this : Let,s view all processes except those that fulfill the specified conditions (negates the selection) :įor the Example – If you want to see only session leaders and processes not associated with a terminal. You can use -d option to view all the processes except session leaders. View all processes except both session leaders and processes not associated with a terminal. View Processes not associated with a terminal If you want to print all the running processes on the screen, use -A or -e option with ps command. Print all active processes on the screen: This is because bash is just a parent process for different processes that need bash for their execution and bash itself is not utilizing any CPU time till now. In the above example, we found that for bash no CPU time has been given. It is nothing but the total accumulated CPU utilization time for any process and 00:00:00 indicates no CPU time has been given by the kernel till now. Note – Sometimes when we execute ps command, it shows TIME as 00:00:00. TIME – the amount of CPU in minutes and seconds that the process has been running.ĬMD – the name of the command that launched the process. TTY – the terminal type that the user is logged into. You can see the following information from above results: Just type ps in the terminal and hit enter, you will get all processes on the screen. You can use ps command without arguments to displays processes for the current shell.
