问题[command-not-found](unix)

command-not-found当在 Kali Linux 中找不到该命令时会问这样的问题：

Command 'co' not found, but can be installed with:
sudo apt install rcs
Do you want to install it? (N/y)

然而，在 Debian 中，它只建议使用以下命令安装软件包

Command 'co' not found, but can be installed with:
sudo apt install rcs

如何让 Debian 要求安装软件包command-not-found？

我已经安装了命令“txpp.py”来运行细胞内粒子模拟。虽然它适用于我的帐户，但当我更改为另一个帐户时，它显示“未找到命令”。我希望收到解决此问题的意见和建议。非常感谢

我在 VirtualBox 中运行最新的 64 位 kali linux，但我无法在任何地方找到 theharvester.py

即使使用定位我也找不到它

并且当我运行安装命令时安装它，我得到以下输出

root@kali:~# apt-get install theharvester
Reading package lists... Done
Building dependency tree       
Reading state information... Done
theharvester is already the newest version (3.1-0kali2).
theharvester set to manually installed.
The following packages were automatically installed and are no longer required:
  libayatana-ido3-0.4-0 libbfio1
Use 'apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 44 not upgraded.

当我在终端运行 theharvester 命令时，我得到

root@kali:/usr/share# theharvester
bash: theharvester: command not found
