Change swap size in Ubuntu

In a nutshell swap is a piece of storage (used from your harddisk) which can be used as additional RAM. If you want to change the size of your swap file just follow the following steps: 1. Turn off all running swap processes bash swapoff -a 2. Resize swap (change XG to the gigabyte size you want it to be) bash fallocate -l XG /swapfile 3. CHMOD swap bash chmod 600 /swapfile 4. Make file usable as swap bash mkswap /swapfile ```` 5. Active the swap filebash swapon /swapfile ```

Some commands may take some time to be executed, just wait patiently for the commands to finish.

To verify your swap size run the following command and you will see the swap size
