Check for running processes that should be restarted.
dnf needs-restarting [-u]
needs-restarting looks through running processes and tries to detect those that use files from packages that have been updated after the given process started. Such processes are reported by this tool.
Note that in most cases a process should survive update of its binary and libraries it is using without requiring to be restarted for proper operation. There are however specific cases when this does not apply.
Only consider processes belonging to the running user.
