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.

Can I just use dd to clone my laptop to a bootable USB stick? (suppo.fi)

I know about Clonezilla and copy pasting partitions with gparted, but can I just use dd to copy a partition with batocera to a USB stick and will it then boot from the stick? Do I have to set the boot flag or take any other steps?

Thank you for any tips.

First tar up your filesystem. You can use gzip to save space. Once that's done copy it over. Make sure you use a good filesystem on the USB device that isn't going to cause data loss. (ie not fat)

Keep in mind that you can't do this live and that copying the archive over will take time and the drive may lie to you. Its always best practice to run sync or eject before unplugging.

I just moved to Linux two days ago and omg there is so much to learn but something I never heard of until 20.minutes ago and again right now is tarring...what is it?

Its a compression program for making file archives.

So basically Zip but better?

[–] possiblylinux127@lemmy.zip 4 points 9 months ago

Its not necessary better as tar by itself doesn't have compression. You need gzip, bzip2 or something else. On modern systems with gnu tar can handle tar with compression.

If your still curious I would look up how to use it.

Tape ARchiver. It just takes a tree of inodes and puts it in one long format that can be written out to tape or stored as a single file.

You mean tearing?
As in video screen tearing?

There is also tar which is a very common archiving system, so tarring=archiving

Stay away from debian/ubuntu if you really want to learn linux. They dictate how you do things so much you will never learn how to do it.

I'm on mind, which I think is Ubuntu but tbh while I'd love to learn I think it is all just too much for me with my workload. I'm enjoying tinkering but I'm getting nowhere.

[–] bartolomeo@suppo.fi 1 points 9 months ago (1 children)

Wait why can't I do it live? Thanks for the tips.

Because it is in use. You technically can hot swap a file system by switching run levels and temporarily switching to a tmpfs but I've never succeeded.
