WSL: Is there a conditional to detect "Open Linux Shell Here" case?

I would change the ~/.bashrc enhancement to something like this:

CurrDir="$(pwd)"
if [[ "$CurrDir" == "$SystemDir" ]]
then
    cd /path/to/sensible-dir-name
Fi

Where $SystemDir is your System32 directory. Always remember how \ and / differ between Windows and Linux paths:

  • Bash script to convert Windows path to Linux path

Suggests using:

sed -e 's#^J:##' -e 's#\\#/#g'

That said in your instance you could probably hard-code the path.
