Exam LX0-103 topic 2 question 9 discussion

swapoff The swapoff command is used to temporarily disable swapping on a device, such as a swap partition or swap file. When swapping is disabled, the operating system will not use the device as a source of virtual memory, and the contents of any memory pages that have been swapped to the device will be lost. To use the swapoff command, you must specify the path to the device that you want to disable, such as /dev/sda2 for a swap partition or /swapfile for a swap file. It is important to note that disabling swapping can have a significant impact on the performance and stability of the system, as the operating system will be unable to use the device as a source of virtual memory. It is recommended to only disable swapping if you have a specific need to do so, and to be cautious when using the swapoff command.
