"rm清除“

Question

我正在删除目录中的一些文件，并且没有注意到是rm输入的，我输入了空终端。但是，那意外地删除了命令。我试图重新安装它，但没有结果：

naveen@naveen-hp:~$ clear

Command 'clear' not found, but can be installed with:

sudo apt install ncurses-bin

naveen@naveen-hp:~$ sudo apt install ncurses-bin
[sudo] password for naveen:

ncurses-bin is already the newest version (6.2-0ubuntu2).

naveen@naveen-hp:~$ clear

Command 'clear' not found, but can be installed with:

sudo apt install ncurses-bin

naveen@naveen-hp:~$ 

我正在使用Ubuntu20.04LTS与Gnome。现在如何恢复这个命令？

Answer 1

如果您删除了所有组件，sudo apt install --reinstall ncurses-bin应该重新安装一个组件。
