sudo apt-get upgrade 和 sudo apt upgrade 都是用来升级 Ubuntu 系统软件包的命令,它们的功能也是相同的。但是,apt upgrade 是 apt 命令的简化版,它更加易于记忆和书写。在 Ubuntu 16.04 及之前的版本中,apt 命令并不是默认安装的,因此需要使用 sudo apt-get upgrade 命令来升级软件包。而在 Ubuntu 16.04 及之后的版本中,apt 命令已经默认安装,因此可以直接使用 apt upgrade 命令来升级软件包。总之,两个命令的作用是一样的,只是书写方式不同。需要注意的是,升级软件包时,两个命令都会提示你确认操作,以避免误操作造成损失。

sudo apt-get updatesudo apt-get upgrade
As an AI language model, I don't have the ability to execute commands like a computer. But here's what these commands do:
- `sudo` is a command that lets you run other commands as a superuser or administrator.
- `apt-get` is a command-line tool used for package management in Ubuntu and other Debian-based Linux distributions.
- `update` updates the package list from the repositories to get the latest version information of packages.
- `upgrade` upgrades all installed packages to their latest versions.
So, when you run `sudo apt-get update`, you update the list of packages available in the repositories, and when you run `sudo apt-get upgrade`, you upgrade all installed packages to their latest versions.
