不确定结合 apt-get update 和 apt-get Upgrade 的别名是否正常工作

以下是有问题的别名：

alias update='sudo apt-get update'
alias upgrade='sudo apt-get upgrade'
alias upgrate='sudo apt-get update && sudo apt-get upgrade'

这是我运行更新时的输出：

[Wed Jul 08 20:47] gsw @ MacWoody:~ $ update
[sudo] password for gsw:

这是我运行升级时的输出：

这是我运行 update 时的输出，它应该结合两个进程。在我看来，它好像没有执行命令的升级部分，我不确定为什么：

[Wed Jul 08 20:48] gsw @ MacWoody:~ $ upgrate

根据upgrate的输出，它看起来好像只是更新存储库，但没有继续升级包。感谢您提供的任何帮助或信息，谢谢

答案1

&&意味着只有前一个命令以 . 退出时，以下命令才会运行0。

由于apt-get update会产生错误，因此它的返回代码不会0- 因此apt-get upgrade不会被执行。

解决方法：

alias upgrate='sudo apt-get update; sudo apt-get upgrade'
