Environment variables in Linux are an important concept that spans most aspects of the operating system, from user applications to system services. Environment variables are used to provide essential information to programs when they are executed. For example, they may contain paths so that the program knows where to find related files or resources. Environment variables can also be used to configure how programs behave, such as setting a preferred language or display resolution.
