gummy: Set the screen pixel brightness to 45%.
$ gummy --brightness ${45}
try on your machine

The provided command, "gummy --brightness ${45}", appears to be using a tool or program called "gummy" to adjust the brightness. However, it seems to have a syntax error.

Typically, with such command syntax, "gummy" is the name of the program or script being executed, while "--brightness" is an option or flag that modifies the behavior of the program. The value associated with the "--brightness" option is usually specified after the option itself.

In this case, the value is denoted as "${45}". The use of "${45}" suggests that it might be a placeholder or variable that holds the value 45. However, the use of curly braces in this context without any preceding dollar sign seems incorrect, as curly braces are typically used for parameter expansion in shell scripting syntax.

To provide a more accurate explanation, it would be helpful to have additional context or information about the specific purpose or functionality of the "gummy" program or tool.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
