This article will explain in detail how to set up exchange files under Linux, Xiaobian thinks it is quite practical, so share it for everyone to make a reference, I hope you can gain something after reading this article.

Create a file of specified size

We need to use dd command to create an empty file of specified size, such as 1G, execute command

dd if=/dev/zero of=/swap bs=1024 count=1048576

In the above command, after "of" is the path where the exchange file is stored. After "bs" is the number indicating the block size. Byte is the unit. Here, it is 1024 bytes, that is, 1KiB. The number after "count" refers to the number of blocks. Formula: Number of blocks * block size = actual size of file.

II. Format the file as an exchange file

execution command

mkswap /swap

The following prompt appears:

Setting up swapspace version 1, size = 1048572 KiBno label, UUID=fefb01a8-6e5b-4e0f-9fde-d7fe3125b86d

III. Enabling Exchange Files

execution command

swapon /swap

Attached:

View swap partition, swap file status

swapon -s#or free

Disable swap partition, swap file

swapoff /swap

(Replace/swap above with the path to your swap partition, file)
