From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Or just cat file.img > /dev/....
I think you should use dd for that?
Why? I am free to use whatever I want. This is not Microsoft Windows.
What
using dd for that is outdated info that everyone keeps blindly parroting with zero understanding why. cat is simpler and works fine.
note: both cat and dd only work for this when the image is made in a compatible way, my linux isos always work fine but a windows iso didnt and needs a more specific tool.
It is not outdated at all.
To be able to pipe to a disk, you have to open a root shell. That's more dangerous than just running a single dd command with toot, as you can forget about it and run other commands that way too.
cat is for writing files, dd for writing disks.
Can you explain how this can work?
No, cat is not for writing files. Cat is for reading files and directing the data to standard output.
With ">" you are directing standard output to a file, in this case a blockdevice.
Cool, need to try that
/dev/sdX
is a file, and bothdd
,cat
can read files in full. You can even try something likezstd
to compress it too.One of the nice things about
dd
though is you can see the progress with--status=progress
