`/usr/bin/xcode-select -printPath` returns below.

```
xcode-select: Error: unknown command option '-printPath'.

xcode-select: Report or change the path to the active
Xcode installation for this machine.

Usage: xcode-select --print-path
Prints the path of the active Xcode folder
or: xcode-select --switch
Sets the path for the active Xcode folder
