Setting environment variables in a computer system is a common Oman Phone Number task for many users. These variables are used to store information that is used by various programs and applications. The two main ways to set environment variables are temporarily and permanently, each with its own advantages and disadvantages.
Setting environment variables temporarily is often done on a per-session basis. This means that the variables are only available for the current session and will be lost once the session is closed or the computer is restarted. This method is useful for situations where a specific variable only needs to be set for a short period of time, such as when running a specific program or script.
For example, suppose you are working on a project that requires a specific directory to be added to the PATH variable in order to access certain executables. By setting the PATH variable temporarily, you can ensure that the directory is added only for the duration of the project, without affecting other programs or applications on your system.
