The path you are in when opening a new WSL tab is determined by startingDirectory.
This parameter needs to be a valid Windows path, which isn’t great if we want to end up in /home/kamner inside WSL.
The nice thing about WSL is that it will resolve windows paths into their equivalent WSL/linux path if possible.
For example, C:\Scripts would resolve to /mnt/c/Scripts.
Using this and the neat trick that the WSL filesystem is exposed as a a hidden fileshare ([[technology/windows/wsl-hidden-fileshare]]) we can get to where we want.
To get the hidden fileshare path of your home directory navigate to it and open it with explorer.exe
cd ~
explorer.exe .
This will give you a strange hidden network share path in explorer. Just use that as startingDirectory and we are all set.
