I created a swap file in Ubuntu by following this process, but I no longer need it, so I would like to delete it.
However, the blog article doesn't write anything regarding the deletion, so I tried deleting it via
sudo rm -rf, but it got the
Operation not permitted error.
So far, I tried many answers to how to delete a file with the same error, but nothing worked in my case:
- Changing Ownership: "Operation not permitted" - even as root!
, which include:
- change the permission of both the swapfile and the root directory
hmod ugo+w .)
- change the immutable flag on both the swapfile and
chattr -i -a .)
- reboot the system
All of them didn't work. I wonder how I can delete it, but if it is a swap file, how can I delete it?
The result of
free -h is:
total used free shared buff/cache available Mem: 1.7G 101M 405M 1.2M 1.2G 1.4G Swap: 1.5G 234M 1.3G
