Linux Tools

Bluetooth Utilities (bluetoothctl) 🔗︎

bluetoothctl is a cli tool that controls bluetooth connections. Here is a sequence of commands that connects a bluetooth device.

scan on: show a list of available devices with their MAC addresses. In this step find the MAC address of the device you are trying to connect. scan off: turn off the scan. pair <MAC>: pair the device. connect <MAC>: connect the device. disconnect <MAC>: disconnect the device.

Audio Utilities 🔗︎

Mostly, amixer is the right cli tool to control audio. However, I would recommend using ‘alamixer’, the front-end tool for amixer. The UI of this tool is intuitive, thus I would not put any instructions there.

GUI 🔗︎

Linux window system is powered by various window managers. Famous window managers include: gnome, kde and i3. Usually, starting a window manager is either by executing startx or run the window manager manually by i3 -r. Window manager is the window system you interact with. However, the start up menu is powered by display manager. Just to name a few: gdm3 for gnome. I would recommend gdm3 as display manager, as it is small enough and easy to install.

Linux Common Locations 🔗︎

Linux has some common locations to store config files and assets. Just to name a few:

• /etc/apt/source.list: containd debian packages repository urls. This config file is useful when managing package versions. Also, /etc/apt/source.list.d/* contains repository urls for external packages. Just to name a few: 1password.
