Visual Studio Code - CodeRunner - Run shellscripts with WSL.

CodeRunner_Settings_WSL.md

Executor for shellscript

We need to convert Windows path to WSL path: C:\Users\user\Documents\script.sh -> /mnt/c/Users/user/Documents/script.sh

 "shellscript": "bash $('/mnt/' + $fullFileName.Substring(0,1).ToLower() + $fullFileName.Substring(2).Replace('\\','/') )",
