#TechTipThursday: find out if your Linux box actually needs a reboot.

After a round of updates the guessing game is always the same. Do I need to reboot, or can I keep working? On Fedora and RHEL based systems, stop guessing:

needs-restarting -r

It checks whether the kernel or core libraries changed and tells you straight up whether a reboot is required. It lives in the dnf-utils package, so install that first if you don't have it.

Package management is one of those things every Linux admin should know cold.

Search for a package:
dnf search packagename

Install it:
dnf install packagename

Check what's installed:
rpm -qa | grep packagename

Remove it cleanly:
dnf remove packagename

Your package manager is your best friend. Treat it accordingly.
