The command "redshift -t ${5700}:${3600}" is used to adjust the color temperature of the display on a computer monitor using the Redshift software. Here is a breakdown of the individual components:

• "redshift" is the name of the command or executable that launches the Redshift software.

• "-t" is an option or flag that indicates we want to specify the color temperature.

• "${5700}:${3600}" is the value being passed to the "-t" option. In Redshift, color temperature is measured in Kelvin. The first value (5700) represents the target color temperature during daylight, while the second value (3600) represents the target color temperature during nighttime or in low-light conditions.

In this example, Redshift is being instructed to set the color temperature of the display to 5700 Kelvin during daylight and 3600 Kelvin during nighttime. This adjustment can help reduce the amount of blue light emitted by the screen, which can potentially improve sleep quality and reduce eye strain in low-light environments.
