How to script in Windows Subsystem for Linux (WSL) and call it from a batch file?
Over on https://askubuntu.com/a/1108609/912537 I suggested a method to edit grub from windows. I have grub installed on /boot/efi/EFI/grub and have been trying to create a script which changes the "next_entry" variable in the Grub Environment Block.
Dual booting Win10 and Debian9, I have WSL running Debian (Bash on Win).
I am trying to use a script as a reboot to Linux shortcut since my BT keyboard doesn't work in GRUB. I have the reverse working from Linux just fine. I have a batch file and a shell script (not) working in tandem. Here is the code:
reboot-to-linux.bat
@echo off
mountvol s: /S
wsl /mnt/c/Users/<username>/Documents/User_scripts/reboot-to-linux.sh
mountvol s: /D
Restart-Computer -Computername 'localhost'
reboot-to-linux.sh
#!/bin/bash
sudo mount -t drvfs s: /mnt/s
sudo grub-editenv /mnt/s/EFI/grub/grubenv set next_entry=0
sudo umount /mnt/s
This is the error I'm getting:
does not existint /mnt/s
grub-editenv: error: cannot open `/mnt/s/EFI/grub/grubenv.new': No such file or directory.
umount: /mnt/s: not mounted
Which tells me that the mount command is failing to mount the s: windows mountpoint onto /mnt/s - weirdly, each of these commands works individually in their respective consoles, I'm obviously not writing the scripts correctly.
What is the correct way to write these scripts?

In fact, both the scripts are functional however the batch commands can be wrapped by the line
@powershell -c " "
to be run from outside a terminal and as for the shell script - don't write your scripts in notepad people. Yes, a rookie mistake, Windows had made me complacent. FYI notepad and other windows editiors use "carriage return, line feed" as their new line (/r/n) and Linux expects just a line-feed (/n) so this breaks the script.
Also, better idea is to store your shell script in the wsl filesystem rather than somewhere in /mnt/c - just keep windows away from it. There you have it - clickable reboot shortcuts from Linux to windows and back again! I think I'll be seeing less and less of Windows these days.
