Answer by Sergey Ponomarev for Golang: tests and working directory

Here is function to find a root project directory that contains .git folder:

import ("os""path/filepath")func FindProjectDir() string {    // Test can be started from command line in project folder or in IDE    // Try to detect a correct path to a project directory    // Find a project dir that contains .git    curDir, _ := os.Getwd()    projectDir := curDir    for {        _, err := os.Stat(projectDir +"/.git")        if err == nil {            return projectDir        }        projectDir = filepath.Dir(projectDir)        if projectDir == "/" { // reached root            return ""        }    }}

You can adapt it and append the file name that you are looking for.Still I think this answer is better https://stackoverflow.com/a/71488632/1049542But sometime you need also to execute some shell script in the project root folder so you need to know the parent folder.
