The command "xbps-install --sync ${package_name1} ${package_name2}" is used in the XBPS package manager, which is the default package manager for Void Linux.

Here's a breakdown of its components:

• "xbps-install" is the command to install packages using XBPS.
• "--sync" is an option that tells XBPS to synchronize the package repositories with the latest versions of packages before installing them.
• "${package_name1} ${package_name2}" are placeholders for the names of the packages you want to install. You would replace these placeholders with the actual names of the packages you want to install.

So, when you run this command, XBPS will synchronize the package repositories and then proceed to install the packages specified by ${package_name1} and ${package_name2}.
