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:
, 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 1.3G1 Answer
The output of free -h indicates that swap is being used - the swap process is still running.
Enter the command
sudo swapoff /path/to/swapfile/to/be/deletedThis will disable the swapfile, and the file can be deleted at that point.
Please note that if you have created an entry in /etc/fstab for the swapfile, you should also delete it (or comment it out by adding # at the beginning of the line).
