One-liner #1
freebsd-version -kru ; uname -aKU
These two commands in sequence display detailed information about your FreeBSD system's version and kernel. It helps to
- Detect version mismatches between kernel and userland (e.g. after patching).
- Confirm if a reboot is pending.
- See detailed kernel version info (compiled vs. running)
One-liner #2
pciconf -lv | grep -B 3 -A 1 display
This one-liner helps you identify the PCI display controller (graphics card) and shows a few lines before and after the line containing the word display for context, including device ID, vendor, and possibly the driver in use.
One-liner #3
pkg repos -el | sort -f ; pkg repos -e
This one-liner prints a sorted list of repository names and full configuration of each repository. This is helpful for debugging, auditing, or confirming what repositories are enabled and how they're configured.
