In a tutorial for developers, Jack Wallen explains the process of setting temporary environment variables in Linux. These variables can be used to facilitate working with scripts or systemwide programs. For example, a temporary variable can be set to easily download the correct application for a specific Linux distribution. Additionally, a URL can be set as an environment variable to work with a script, allowing developers to modify the variable without editing the script itself. By using the “export” command in a terminal window, users can set and modify environment variables in Linux.
Setting temporary environment variables in Linux can streamline workflow for developers. By creating variables that can be easily modified, developers can avoid the need to constantly edit scripts. Furthermore, these environment variables can be utilized by any type of script or application, making them highly versatile for various programming tasks. By utilizing the “export” command, developers can define temporary variables and verify their values using the “echo” command. This method of setting temporary environment variables is a valuable tool for developers looking to work smarter, not harder.
