Globs可以匹配多个文件，因此最好将它们存储在一个数组中：

#!/bin/bash
shopt -s nullglob globstar    # Enable recursion and zero matching
directories=( **/SRC/Code )
case "${#directories[@]}" in
    1) echo "Found the directory: ${directories[0]}" ;;
    0) echo "There were no matches..." ;;
    *) echo "There was more than one match!" ;;
esac
