The command "snap refresh ${package_name}" is used to update a specific snap package on a system running Linux.

In Linux, snap packages are self-contained software bundles that include all the necessary dependencies to run on different distributions. They are designed to provide a secure, isolated environment for applications.

The "snap refresh" command is used to update snap packages installed on a system. By specifying "${package_name}", you indicate the particular package you want to update. This could be the name of an application or software package that has been installed using the snap package manager.

When you execute this command, it will check if a new version of the specified package is available. If an update is found, it will download and install the latest version of the package, replacing the older version on your system.

It is important to note that the "${package_name}" should be replaced with the actual name of the package you want to update. You can find the correct name by running the command "snap list" which will display a list of installed snap packages along with their names.
