reenice

Reenice is a term used to describe the act of undoing or reversing a previous action, often in a computing or digital context. It is the opposite of "nice," which in computing parlance can refer to setting the priority of a process. Therefore, "reenice" implies lowering the priority of a process that may have previously been elevated, or perhaps even applying a negative priority if the system allows for it.

The specific implementation and functionality of reenice can vary significantly between different operating systems and scheduling algorithms. In Unix-like systems, the `nice` command is used to start a process with a given scheduling priority, and the `renice` command is used to change the priority of an already running process. A lower nice value indicates a higher priority, meaning the process will receive more CPU time. Conversely, a higher nice value indicates a lower priority, causing the process to receive less CPU time.

Users might reenice a process to free up system resources for more critical tasks. For example, if a background task is consuming too much CPU and slowing down interactive applications, a user could reenice the background task to a lower priority. This allows the foreground applications to run more smoothly without completely stopping the background process. The concept is primarily concerned with process management and resource allocation on a computer system.
