Usage: neofetch --option \"value\" --option \"value\"

Neofetch is a CLI system information tool written in BASH. Neofetch
displays information about your system next to an image, your OS logo,
or any ASCII file of your choice.

NOTE: Every launch flag has a config option.

Options:

INFO:
    --disable infoname          Allows you to disable an info line from appearing
                                in the output.

                                NOTE: You can supply multiple args. eg. 'neofetch --disable cpu gpu'

    --os_arch on/off            Hide/Show OS architecture.
    --speed_type type           Change the type of cpu speed to display.
                                Possible values: current, min, max, bios,
                                scaling_current, scaling_min, scaling_max

                                NOTE: This only supports Linux with cpufreq.

    --speed_shorthand on/off    Whether or not to show decimals in CPU speed.

                                NOTE: This flag is not supported in systems with CPU speed less than
                                1 GHz.

    --cpu_brand on/off          Enable/Disable CPU brand in output.
    --cpu_cores type            Whether or not to display the number of CPU cores
                                Possible values: logical, physical, off

                                NOTE: 'physical' doesn't work on BSD.

    --cpu_speed on/off          Hide/Show cpu speed.
    --cpu_temp C/F/off          Hide/Show cpu temperature.

                                NOTE: This only works on Linux and BSD.
