Config Files

Boot options

One use of a config file is to set boot flags to execute without having to state them when launching the program.

• This is set under the [flags] section.
• These options are generally the same as the long names as other flags (ex: case_sensitive = true).
• Note that if a flag and an option conflict, the flag has higher precedence (ex: if the -c and temperature_type = kelvin both exist, the Celsius temperature type is ultimately chosen).
• For temperature type, use temperature_type = "kelvin|k|celsius|c|fahrenheit|f".
• For default widgets, use default_widget = "cpu_default|memory_default|disk_default|temperature_default|network_default|process_default".

Colours

Another use is to set colours, under the [colors]. The following labels are customizable with strings that are hex colours, RGB colours, or specific named colours.

Supported named colours are one of the following: Reset, Black, Red, Green, Yellow, Blue, Magenta, Cyan, Gray, DarkGray, LightRed, LightGreen, LightYellow, LightBlue, LightMagenta, LightCyan, White

Labels	Details	Example
Table header colours	Colour of table headers	table_header_color="256, 256, 256"
CPU colour per core	Colour of each core. Read in order.	cpu_core_colors=["#ffffff", "blue", "122, 122, 122"]

SWAP	The colour SWAP will use	swap_color="#111111"
RX	The colour rx will use	rx_color="#ffffff"
TX	The colour tx will use	tx_color="#111111"
Widget title colour	The colour of the label each widget has	widget_title_color="#ffffff"
Border colour	The colour of the border of unselected widgets	border_color="#ffffff"

Note some colours may not be compatible with the terminal you are using. For example, macOS's default Terminal does not play nice with many colours.

Default config locations

bottom will check specific locations by default for a config file.

• For Unix-based systems: $HOME/.config/bottom/bottom.toml.
• For Windows: {FOLDERID_RoamingAppData}\bottom\bottom.toml (for example, C:\Users\Clement\AppData\Roaming\bottom\bottom.toml).
