如何在CentOS 7中安装Snapd
用法:snap [OPTIONS] <command>
Install, configure, refresh and remove snap packages. Snaps are 'universal' packages that work across many different Linux systems,enabling secure distribution of the latest apps and utilities for cloud, servers, desktops and the internet of things.
This is the CLI for snapd, a background service that takes care of snaps on the system. Start with 'snap list' to see installed snaps.
