Hi,
I’ve been toying with grub, and I didn’t backup the file ‘/etc/grub.d/10_linux’.
The reason I was changing it, was due to the dodgy looking grub entries… they displayed weird things.
eg. 'EndeavourOS on Linux on linux"
If someone can provide an updated version of the ‘/etc/grub.d/10_linux’ file, that hasn’t got this issue, that would be great, otherwise could somebody post the contents of a default file? I can’t find it on the github.
Cheers
You can just reinstall grub. That will bring the default file back.
sudo pacman -S grub
As a side note, modifying that file is fairly pointless as your changes will be overwritten every time the package updates.

It doesn’t live in github in an absolute sense.
The source file is in the grub git repo but it is patched by the Arch PKGBUILD. You could extract it from the Arch package but it would probably just be easier to reinstall the grub package as recommended above.
Ahh ok, good to know. I’ll try that.
So whats the alternative… for more ‘permanent’ changes without using grub-customizer…
I’ve been looking around the forums, and grub-customizer has a fairly bad name, to say the least 
You could create an alpm hook to modify the file when the package changes. That is what EndeavourOS was doing before we decided to not do that anymore.
This is the sed statement that was being used to do that:
sed -i /etc/grub.d/10_linux \
-e "s|s, with Linux |s, on |" \
-e 's|"Loading Linux |"Loading kernel |' \
-e 's|^ OS="${GRUB_DISTRIBUTOR} Linux"$| OS="${GRUB_DISTRIBUTOR}"|'
It is worth noting that if the file 10_linux changes this may stop working or have unexpected impact.
Ahh I see.
I just googled alpm hooks, and they look fairly interesting.
Here’s the link for future viewers that are interested: alpm-hooks (ArchLinux docs)
Thank you @dalto for explaining these things, I’m learning so much.
I’ll mark this thread as solved, but just out of curiousity, what were the entries in the grub menu supposed to look like… (obviously, assuming they were not supposed to display things like I mentioned before)
I am not sure what you mean. The file provided upstream from grub really does name them that way. It seems to be intentional. However, it looks worse in this case because Arch names it’s kernel “linux”. Normally, that last linux would be the name of the kernel.
That actually does answer my question. Thank you
