For the time being, deactivate the swap file and delete it (actually this is not necessary because you will overwrite it) sudo swapoff / swapfile sudo rm / swapfile.Create a new swap file of the desired size. Thanks for using Hackinet, I can use sudo fallocate -l 4G / swapfile to create a 4GB swap file.
[Updated Jul 26, 2020]: change the permission to install the swap file; Swap file if / etc / fstab.
Swap is a special area on your computer that the operating system can use as additional memory.
Since Ubuntu 17.04, the swap has been split by the swap file. The main advantage of the paging file is still that it is easy to edit.
Note. Be sure to back up your data before executing the following commands!
In one of the following examples, we expand the available editable space in the / swap file, including 4 GB, to 8 GB.
- Rotate with all trade
if = file input
from = output = file
area size bs
number = block multiplier
Let everyone exchange. sudo swapoff -a.Resize the paging file. sudo dd if = / dev / zero of = / swapfile bs = 1M count = 1024.Create the required swap file. sudo mkswap / swap file.Repurchase again. sudo is a swap / swap file.
6. Edit / etc / fstab and add another swap file if it doesn’t already exist
sudo dd if = / dev / zero of = / swapfile bs = 1G count = 8
/ swapfile probably no swap sw 0 0
grep SwapTotal / proc / meminfo
Nowadays, the paging file plays an important role in Linux. This is not a required option, but unfortunately it is very important that it has a number of goals. Usually, when you have a system, you need to specify the size of the exchange directory. The recommended size is still 4 GB, which can be reduced or increased relative to each other as needed. Today let’s take a look at how the swap size changes in Ubuntu.
Note. All of these commands require basic privileges to run, so I recommend running the “root” terminal.
Before changing the exchange, let’s see how many exchanges we have.
As a result, the system has an important swap file under “/ swap file”. Pen
For this swap file, we need to deactivate it first.
Here the total paging file size is slightly larger bs * count = 1M x 4096 equals 4GB
Remove Swap File
Disable all sudo swapoff -a swap tactics.Change the swap size (from 512 MB to 8 GB)Make the declaration usable as a swap file sudo mkswap / swapfile.Include most of the swap files sudo swapon / swapfile.Check the swap space often with grep SwapTotal / proc / meminfo.
If you have enough RAM, you probably want to get rid of the entire swap file. If that’s your reason, let’s get rid of the main swap file!
Don’t worry! I will also show the audience how to create an unmistakably fresh swap file.
Remove the swap file entry from the “/ etc / fstab” file. This should be the last line of this file.
To get the replacement file, use the following instructions –

# Add permission so only the person sitting at the root can read the swap file
Edit the / etc / fstab file frequently and generally add a one-time line to the end of the file –
What if you had this swap partition? Actions with the section must be performed independently. This is more tedious than just handling the swap files with the above methods, isn’t it?
Deactivate an existing exchange area.Create your own new swap partition of the desired size.Read the section table again.Be sure to configure the partition as a swap area.Add a new spanked section / etc / fstab.Activate the exchange.
I recommend removing this swap partition and using the crossover method to create a new replacement file.

Why Do I Need To Make Sure You Have Completed The CAPTCHA?
Filling in the CAPTCHA shows that you are human and gives you temporary access to a huge amount of Internet resources.
What Can I Do To Prevent This From Happening Again In The Future?
If you have a working personal connection, for example at home, the client can run a virus scan on your device to make sure the concept is not infected with malware.
Another way to increase the size of the swap is to use someone else’s GParted partition editor. In short, you and your family resize the swap partition, then hit the power button and go swap. You should only be able to increase the size of the swap partition ifae if there is unallocated time before or after the Exchange section.
If someone is in the office or on the internetwork, you can ask the cell phone network administrator to scan the network for infected devices that are incorrectly configured.
Another way to prevent this unique site from appearing in the future is to use the Privacy Pass. You may now need to download version 2.0 from the Firefox Add-on Store.
