The command "swapon -L ${swap1}" is used to enable a swap partition on a Linux system.
Here's a breakdown of the different parts:
-
"swapon" is the command used to enable swapping. Swapping is a technique in which idle memory pages are moved from the main memory (RAM) to a dedicated area on the hard drive called the swap space, to free up memory for other processes.
-
"-L" is an option for the "swapon" command. It specifies that you want to enable a swap partition by using a label instead of a device file.
-
"${swap1}" is a placeholder for the label name of the swap partition. It indicates that you should replace "${swap1}" with the actual label name of the partition you want to enable as swap. For example, if your swap partition has the label "swap01", you would replace "${swap1}" with "swap01" in the command.
Overall, this command is used to enable a specific swap partition identified by its label, allowing the system to use it for memory swapping purposes.
