Change swap size in Ubuntu

Starting with Ubuntu 17.04, the swap partition is replaced with a swap file, which makes it easy to be resized. NOTE: Most of the commands below will require root privilege. You can check your current swap size with swapon -s or free -h By default, the swapfile is /swapfile with file mode 600 and it belongs to the root user. ls -lh /swapfile If you want to resize your swapfile, it’s simple.
