### f-strings

If you are not familiar with the `f"userprofile::{username}"`, it is a Python "<a href="https://docs.python.org/3/glossary.html#term-f-string" class="external-link" target="_blank">f-string</a>".

// On Windows, it returns %USERPROFILE%.
// On Plan 9, it returns the $home environment variable.
//
// If the expected variable is not set in the environment, UserHomeDir
// returns either a platform-specific default value or a non-nil error.
func UserHomeDir() (string, error) {
	env, enverr := "HOME", "$HOME"
	switch runtime.GOOS {
	case "windows":
		env, enverr = "USERPROFILE", "%userprofile%"
	case "plan9":

declare -r java_opts=( "${ACTIVATOR_OPTS[@]}" "${SBT_OPTS[@]}" "${JAVA_OPTS[@]}" "${java_opts[@]}" )

if is_cygwin; then
  # cygwin sets home to something f-d up, set to real windows homedir

The _outcome label_ `FROM-CACHE` lets the user know that Gradle has fetched the task results from the local build cache.

The local Gradle Build Cache is located at:

- **On Windows**: %USERPROFILE%\.gradle\caches
- **On OS X / UNIX**: ~/.gradle/caches/

Gradle will periodically clean up the local build cache directory by removing entries that have not been used recently to conserve disk space.

	devnull=<value of os.DevNull>
	goversion=<current Go version; for example, 1.12>

On Plan 9, the variables $path and $home are set instead of $PATH and $HOME.
On Windows, the variables $USERPROFILE and $TMP are set instead of
$HOME and $TMPDIR.

The lines at the top of the script are a sequence of commands to be executed by
a small script engine configured in ../../script_test.go (not the system shell).

Copy the existing private key and public certificate to the `certs` directory. The default certs directory is:

* **Linux:** `${HOME}/.minio/certs`
* **Windows:** `%%USERPROFILE%%\.minio\certs`

**Note:**

* Location of custom certs directory can be specified using `--certs-dir` command line option.
