opkg: Upgrade all the installed packages.
$ opkg upgrade
try on your machine
The command "opkg upgrade" is used in the OpenWrt operating system to upgrade the installed packages to their latest versions.
OpenWrt uses the package management system called "opkg" to handle installation, upgrading, and deletion of software packages. When you run the "opkg upgrade" command, it checks the available package repositories to find updated versions of the installed packages. It then downloads and installs the updated versions, replacing the older versions on your system.
This command is useful to keep your OpenWrt system up to date with the latest bug fixes, security patches, and new features included in the updated packages. Updating packages regularly can improve the stability, security, and performance of your system.
