// EXERCISE: Find and write the names of subdirectories to a file
|
|
//
|
|
// 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.
|
|
//
|
|
// Check out its documentation:
|
|
//
|
|
// go doc os.FileInfo.IsDir
|
|
//
|
|
// # or using godocc
|
|
// godocc os.FileInfo.IsDir
|
|
//
|
|
// + You can use '\t' escape sequence for indenting the subdirs.
|
|
//
|
|
// + You can find a sample directory structure under:
|
|
// solution/ directory
|
