List restartable programs or services using deleted libraries after upgrades

pip install restartable==0.9.0



List running processes using files deleted by recent upgrades

Build Status

When upgrading packages, the package manager won't restart services or programs that depend on some updated library, for obvious reasons. This has security implications in the case of outdated libraries still in use.

OpenSUSE has a cool zypper ps command to check for programs and services using deleted files. It's also available in other distros as zypp-CheckAccessDeleted from the libzypp package. Those commands parse lsof output and check /proc/<pid>/cgroup to extract the service names.

Here's a Python version that checks /proc/<pid>/maps, extracting information from other files in /proc/<pid>.

No lsof dependency needed.

Excerpt from zypper manual:

After each upgrade or removal of packages, there may be running processes on the system which continue to use meanwhile deleted files. zypper ps lists all processes using deleted files, together with the corresponding files, and a service name hint, in case it’s a known service. This gives a hint which services may need to be restarted after an update. Usually programs which continue to use deleted shared libraries. The list contains the following information:

PID ID of the process
PPID ID of the parent process
UID ID of the user running the process
Login Login name of the user running the process
Command Command used to execute the process
Service Service name, if command is associated with a system service
Files The list of the deleted files


sudo pip3 install restartable

  • Verified to work on Python 3.5+
  • You must run it as root to see the information you want.
  • The output is different from zypper ps to be easily parseable


  • The service names can only be extracted if started by Systemd
