[SOLVED] Smart way to enter UUID to esp/loader/entries/arch.conf

When i install Arch Linux and get to the bootloader (usually i use systemd-boot) and specify UUID on the options line.
I actually take a picture of my root partition's UUID with my phone and enter it manually along with the other lines

title   Arch Linux
linux   /vmlinuz-linux
initrd  /intel-ucode.img
initrd  /initramfs-linux.img
options root=UUID=12345-67890-1234-123456-7890 rw

How do you manage entering UUID or PARTUUID? Is there a smarter way to minimize the risk of typos? Like passing blkid entry for the root partition via some command or likewise?

If you need the output of blkid so that you can write it to a file, consider appending the data using

blkid >> targetfile

and then firing up an editor like vim to modify the file for your needs. (I'm not sure if you can use the system clipboard from a tty)

From my bash_history during my last install:

blkid | awk '/sdb2/' >> /boot/loader/entries/backup.conf

Re: [SOLVED] Smart way to enter UUID to esp/loader/entries/arch.conf

shell:  lsblk -no UUID /dev/sdb2
vi(m):  :r! lsblk -no UUID /dev/sdb2

edit: could even do -Po

edit2: if the partition is mounted then you could use findmnt to remove one additional source of potentional confusion.

I just use copy and paste in my terminal window - but then again all of my installs that aren't scripted are done over ssh
