package main

// ---------------------------------------------------------
// EXERCISE: Print the directories
//
//  Create a program that can get multiple directory paths from
//  the command-line, and prints only their subdirectories into a
//  file named: dirs.txt
//
//
//  1. Get the directory paths from command-line
//
//  2. Append the names of subdirectories inside each directory
//     to a byte slice
//
//  3. Write that byte slice to dirs.txt file
//
//
// EXPECTED OUTPUT
//
//   go run main.go
//     Please provide directory paths
//
//   go run main.go dir/ dir2/
//
//   cat dirs.txt
//
//     dir/
//             subdir1/
//             subdir2/
//
//     dir2/
//             subdir1/
//             subdir2/
//             subdir3/
//
//
// HINTS
//
//   ONLY READ THIS IF YOU GET STUCK
//
//   + Get all the files in a directory using ioutil.ReadDir
//     (A directory is also a file)
//
//   + You can use IsDir method of a FileInfo value to detect
//     whether a file is a directory or not: go doc os.FileInfo.IsDir
//
//   + You can use '\t' escape sequence for indenting the subdirs.
//
//   + You can find a sample directory structure under:
//     solution/ directory
