To update packages and apply security upgrades in FreeBSD, you can use the pkg command or the freebsd-update command.
To update packages using pkg, use the update option:
pkg update
This will update all installed packages to the latest available versions.
To upgrade the system to the latest available security patches and updates, you can use the freebsd-update command. First, update the freebsd-update database by running the following command:
freebsd-update fetch
This will download information about available updates from the FreeBSD servers.
Next, install the updates by running the following command:
freebsd-update install
This will apply the updates to the system.
It's important to note that the freebsd-update command will only update the base system, which includes the kernel, system libraries, and core utilities. It will not update third-party packages that you have installed using the pkg command. To update these packages, you will need to use the pkg command.
It's also a good idea to reboot the system after applying updates to ensure that the changes take effect. You can reboot the system by running the reboot command.
reboot
