How to delete a swap file?
I was trying to delete the swapfile on a digital ocean virtual server using the instructions given here: https://www.digitalocean.com/community/questions/delete-swap-file However, when I type: sudo rm /swapfile I get the following error: rm: cannot remove `swapfile': Operation not permitted I have changed the permissions on the swap file to 777 and I believe I have root privileges. I still cannot delete it. It may be helpful to know that I created this instance of a server from an image of another server that I had configures. The swap was enabled in that original server. How do I delete this file? Thank you.
