redshift 命令，可以根据周围环境调整屏幕的色温。
redshift 命令安装：
-bash/zsh: redshift command not found # Windows (WSL2) sudo apt-get update sudo apt-get install redshift # Debian apt-get install redshift # Ubuntu apt-get install redshift # Alpine apk add redshift # Arch Linux pacman -S redshift # Kali Linux apt-get install redshift # Fedora dnf install redshift # OS X brew install redshift # Raspbian apt-get install redshift # Dockerfile dockerfile.run/redshift # Docker docker run cmd.cat/redshift redshift
redshift 命令补充说明：
redshift 会根据周围环境调整屏幕的色温。如果晚上在屏幕前工作，可能可以减轻眼睛不适。redshift 程序的灵感来自 f.lux（请参阅这篇文章，了解 redshift 项目的原因）。
redshift 命令语法：
redshift -l LAT:LON -t DAY:NIGHT [OPTIONS...]
redshift 命令选项：
-h
Display this help message
-v
Verbose output
-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 continously adjust 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
redshift 命令实例：
设置 redshift ，白天温度为 5700K，晚上温度为 3600K：
redshift -t 5700:3600
使用手动指定的自定义位置打开 redshift：
redshift -l latitude:longitude
白天打开 redshift，屏幕亮度为 70%，晚上亮度为 40%：
redshift -b 0.7:0.4
使用自定义伽马级别（0 到 1 之间）来打开 redshift：
redshift -g red:green:blue
redshift，保持色温恒定不变：
redshift -O temperature
