minicom:tldr:d600a
The command "sudo minicom --device ${-dev-ttyUSB0}" is used to run the "minicom" program with elevated privileges (using "sudo").
Explanation of each part:
-
"sudo": It is a command in Unix-like operating systems (including Linux) that allows a user with proper permissions to run commands as a superuser or another user.
-
"minicom": It is a communication program used for connecting to and controlling devices such as modems, routers, and serial consoles. It provides a terminal interface for interacting with these devices.
-
"--device ${-dev-ttyUSB0}": This part is the option to specify the device that minicom should connect to. In this case, it is using the placeholder "${-dev-ttyUSB0}", which is likely a typo and should be changed to "$DEV/ttyUSB0" to specify the device "/dev/ttyUSB0".
- "/dev/ttyUSB0": It represents the device file for a USB-to-Serial adapter. In this case, it assumes that the USB device is connected to the USB port 0 and assigned the "ttyUSB0" identifier. This could vary depending on the system and the number of USB-to-Serial devices connected.
To summarize, the command "sudo minicom --device ${-dev-ttyUSB0}" runs the "minicom" program with superuser privileges and connects to the device specified by "/dev/ttyUSB0" (assuming the correct modification is made to the device option).
