dpkg -l lists all the installed programs on a Debian apt based system. There are too many to list all and many are built in system commands.

Below are some that I highlight for interest and future reference to easily find on reinstall.

• fastfetch Fastfetch is a neofetch-like tool for fetching system information and displaying it prettily. It is written mainly in C, with performance and customizability in mind. Also see Deep Dive With Fastfetch; a Neofetch Alternative

I have been using the Python package management software pipx. Below are some listed of interest.

• sudo apt install pipx (pipx — Install and Run Python Applications in Isolated Environments)
• pipx ensurepath
• pipx install glances (https://nicolargo.github.io/glances/|Glances]])
• pipx inject glances "glances[web]" (Glances webui with pipx)

As can be seen glances uses pipx this is a good reference that explains some use of pipx commands, Pipx: Installing, Uninstalling, & Upgrading Python Packages in Virtual Envs. Some key ones are:

• pipx list to list the installed python packages under pipx
• pipx upgrade package to upgrade a python package under pipx
• pipx uninstall package to uninstall a pipx package

Some python packages:
