System Info

Summary

This note is a quick reference for Fedora Atomic host checks that do not belong in the broader Linux command layer.

firefox & → open application from terminal (with &: process runs detached)
systemctl status sshd → shows service status
systemctl restart sshd → restart sshd
systemctl poweroff → power off via terminal
systemctl reboot → reboot via terminal
systemctl hibernate → hibernate via terminal
systemctl suspend → suspend via terminal
journalctl -xe → shows system logs
journalctl -b → shows system logs
rpm-ostree status→ shows what image/deployment you’re booted into, what’s queued next, and what you can roll back to (plus layered packages)
rpm-ostree status | grep -A3 -E 'Pending|LayerPackages' → show any rpm-ostree status lines containing either “Pending” or “LayerPackages”, plus the next 3 lines after each match, so you see the related details |→ a pipe: sends the output of rpm-ostree status into the next command as input -E→ use extended regex (so | works as “OR” without needing backslashes) -A3→ “After context”: when a line matches, also print the next 3 lines after it (useful because rpm-ostree info spans multiple lines)
vainfo → checks VA-API hardware video acceleration by listing the loaded VA driver and supported codec profiles/entry points

rpm-ostree status
journalctl -b
systemctl status sshd
vainfo

general Linux host identity checks now live in Linux System Info
this note stays focused on Atomic-specific host state and a few workstation checks that matter more in this Fedora setup
rpm-ostree status is one of the key checks here because it reflects the Atomic deployment model directly
