How do i check if the system needs rebooting after a yum update?

  • Man page for yum-utils.

    Note: The command is part of the yum-utils.

    This is what you see before updating the machine.

    $ sudo needs-restarting  -r
    No core libraries or services have been updated.
    Reboot is probably not necessary.

    After updating the system.

    $ sudo needs-restarting  -r
    Core libraries or services have been updated:
      glibc -> 2.17-260.el7_6.3
      dbus -> 1:1.10.24-13.el7_6
      openssl-libs -> 1:1.0.2k-16.el7_6.1
      systemd -> 219-62.el7_6.5
      linux-firmware -> 20180911-69.git85c5d90.el7
      kernel -> 3.10.0-957.10.1.el7
    Reboot is required to ensure that your system benefits from these updates.
