[SOLVED] Errors when running grub-mkconfig -o /boot/grub/grub.cfg

Hi,
I recently completely reinstalled Arch. Everything works fine like before excepted for grub. When I launch the command grub-mkconfig -o /boot/grub/grub.cfg, I get this error:

Generating grub configuration file ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/intel-ucode.img /boot/initramfs-linux.img
Found fallback initrd image(s) in /boot: initramfs-linux-fallback.img
error: out of memory.
error: syntax error.
error: Incorrect command.
error: syntax error.
Syntax error at line 162
Syntax errors are detected in generated GRUB config file.
Ensure that there are no errors in /etc/default/grub
and /etc/grub.d/* files or please file a bug report with
/boot/grub/grub.cfg.new file attached.

After installation I edited the config to make it more comfortable so I first thought it was my config that was buggy.
But after a pacman -Rs grub and pacman -S grub to clear the config, the error still persists.
I tested each file in /etc/grub.d/ and no one is faulty neither /etc/default/grub.
Line 162 points to the last line of /boot/grub/grub.cfg.new which is the part included from /etc/grub.d/41_custom
I read on many topics that adding GRUB_DISABLE_SUBMENU=y at the end of /etc/default/grub resolves the issue but it does not works for me hmm
All the grub configs are the default ones.

EDIT:
Here's /boot/grub/grub.cfg.new's content:

Re: [SOLVED] Errors when running grub-mkconfig -o /boot/grub/grub.cfg

report with /boot/grub/grub.cfg.new file attached.

I assume it would be really helpful to see that file …

Re: [SOLVED] Errors when running grub-mkconfig -o /boot/grub/grub.cfg

Add a trailing newline to /etc/grub.d/40_custom

Re: [SOLVED] Errors when running grub-mkconfig -o /boot/grub/grub.cfg

Ok that's just that yikes
I've seen it earlier but don't thought it might be that
Also when I reinstalled grub, pacman copied 40_custom to 40_custom.pacsave so it continued to make grub-mkconfig fail.
Thank you seth smile

Re: [SOLVED] Errors when running grub-mkconfig -o /boot/grub/grub.cfg

"fi#foo" is not a valid token, so the branch isn't closed and the script shits itself.
Better editors (and emacs ;-) can handles that for you - some even do it by default.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Re: [SOLVED] Errors when running grub-mkconfig -o /boot/grub/grub.cfg

I use nano (sometimes vim wink) to edit files and I've seen earlier that it appends a newline automatically so it's weird that it didn't do it here hmm
