redshift (5)

A configuration file with the name `redshift.conf' can optionally be placed in `~/.config/'. The file has standard INI format. General program options are placed under the `redshift' header, while options for location providers and adjustment methods are placed under a header with the name of that provider or method. General options are:

temp-day = integer

Daytime temperature

temp-night = integer

Night temperature

transition = 0 or 1

Disable or enable transitions

brightness-day = 0.1-1.0

Screen brightness at daytime

brightness-night = 0.1-1.0

Screen brightness at night

gamma = R:G:B

Gamma adjustment to apply

adjustment-method = name

Select adjustment method. Options for the adjustment method can be given under the configuration file heading of the same name.

location-provider = name

Select location provider. Options for the location provider can be given under the configuration file heading of the same name.

Options for location providers and adjustment methods can be found in the help output of the providers and methods.

Example for Copenhagen, Denmark:

• $ redshift -l 55.7:12.6 -t 5700:3600 -g 0.8 -m vidmode -v

An example configuration file with the same effect as the above command line:

• [redshift]
  temp-day=5700
  temp-night=3600
  gamma=0.8
  adjustment-method=vidmode
  location-provider=manual
