title: Create a dummy file with a specific size
How to create dummy files with a specific size using the “dd” command:
The “dd” command can be used to create a file of a specific size. This is useful if you would like to test download speeds, or any other tests, and need a file of a specific size.
dd if=/dev/zero of=file_name.txt bs=1024k count=10
This will create a file of 10MB called file_name.txt.
bs is your byte size and count represent the number of blocks. An easy way to look at is 1024K X 10.
Here is an even simpler way to create a 1MB file:
dd if=/dev/zero of=file_name.txt bs=1MB count=1
