I typed in dd in bash and ran it without double checking. Will this do anything to my system?
I just executed dd by itself. Was trying to backup a Raspberry Pi device, which I managed to do using dd. Just stupidly input and execute dd by itself afterwards.
I'm wondering what the difference is between creating a swapfile with
fallocate -l 1G /swapfile
and
dd if=/dev/zero of=/swapfile bs=1024 count=1024
both seem to work fine, but does one have an advantage over the other?
The only thing I could find online was that fallocate does not work on all file systems.
I'm using dd to copy an image onto a USB. But what does dd stand for?
I understand its use, but not what the name dd actually means, or is an acronym for.
It doesn't even say in the man page.
dd is a wonder. It lets you duplicate a hard drive to another, completely zero a hard drive, etc. But once you launch a dd command, there's nothing to tell you of its progress. It just sits there at the cursor until the command finally finishes. So how does one monitor dd's progress?
I have to dd a couple of 1TB hard drives. They are taking several hours to clone and I was wondering if there was any way possible of knowing how fast they are going, how much they have done and how long will they take to copy the rest.
All I can see is the terminal with the command running. When I run ps -e at least I know that dd is working from the CPU usage shown, but I have no way of knowing how much it has done or how long it will take to finish.
Kind of makes me crazy.
