我正在删除目录中的某些文件,没有注意到输入了 rm,我输入了 clear 来清空终端。但是,这不小心删除了该命令。我尝试重新安装它,但无济于事:
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).

我正在使用带有 Gnome 的 Ubuntu 20.04LTS。现在如何恢复该命令?

sudo apt install --reinstall ncurses-bin
如果您删除了一个组件,则应该重新安装所有组件。
