To create a large 1 GB binary image file with the dd
command on a Linux or UNIX system, you can use the following command:
dd if=/dev/zero of=OUTPUT_FILE bs=1M count=1024uoSrce:www.lautturi.com
Replace OUTPUT_FILE
with the desired filename for the image file.
This command will create a new file named OUTPUT_FILE
that is 1 GB in size. It does this by reading 1024
1 MB blocks of zeros from the /dev/zero
device and writing them to the output file.
You can also use the /dev/urandom
device to create a file filled with random data instead of zeros. For example:
dd if=/dev/urandom of=OUTPUT_FILE bs=1M count=1024
