redshift
REDSHIFT(1) User Commands REDSHIFT(1) NAME
redshift - Set color temperature of display according to time of day. SYNOPSIS
redshift -l LAT:LON -t DAY:NIGHT [OPTIONS...] DESCRIPTION
redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night. The color temperature is set according to the position of the sun. A different color temperature is set during night and daytime. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt. OPTIONS
-h Display this help message -v Verbose output -V Show program version -b N Screen brightness to apply (max is 1.0) -c FILE Load settings from specified configuration file -g R:G:B Additional gamma correction to apply -l LAT:LON Your current location -l PROVIDER Select provider for automatic location updates (Type `list' to see available providers) -m METHOD Method to use to set color temperature (Type `list' to see available methods) -o One shot mode (do not continuously adjust color temperature) -O TEMP One shot manual mode (set color temperature) -x Reset mode (remove adjustment from screen) -r Disable temperature transitions -t DAY:NIGHT Color temperature to set at daytime/night The neutral temperature is 6500K. Using this value will not change the color temperature of the display. Setting the color temperature to a value higher than this results in more blue light, and setting a lower value will result in more red light. Default values: Daytime temperature: 5500K Night temperature: 3700K Please report bugs to <https://bugs.launchpad.net/redshift> SEE ALSO
