While running the blog server on Fedora Linux I found out that some one liners are either very important to be executed once or very useful periodically.
Here are some of my most used one-liners
Updating packages
Note that I allow dnf to skip broken packages and delete if necessary. Sometimes if using other than the officials repos you get into all kind of issues.
dnf update -y --allowerasing --skip-brokenUpdating to a new version
This is the command to update to Fedora 39. Note again I allow dnf to try to fix stuff.
dnf system-upgrade download --refresh --releasever=39 --allowerasing --skip-brokenClean all logs
Logs are good but sometimes on a server they tend to eat up a lot of space. Sometimes doing upgrades is difficult due to lack of space caused by the huge system logs (tens of GB). To clean all logs up to the last second execute this.
journalctl --vacuum-time=1sDisable suspend and hibernation
You really do not want suspend or hibernate on a server !!!
systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
