package main
// ---------------------------------------------------------
// EXERCISE: Path Searcher
//
// Your program should search inside the path environment
// variable.
//
// Remove the corpus constant then get the corpus from the
// environment variable "Path" or "PATH".
//
// HINTS
// 1. Search the web to find out what is an environment
// variable and how to use it (if you don't know
// what it is already).
//
// 2. Look up for the necessary functions for getting
// an environment variable. It's in the "os" package.
//
// Search for it on the Go online documentation.
//
// 3. Look up for the necessary function for splitting
// the path variable into directory names.
//
// It's in the "path/filepath" package.
//
// EXAMPLE
// For example, on my Mac, my PATH environment variable
// looks like this:
//
// "/usr/local/bin:/sbin:/Users/inanc/go/bin"
//
// So, if the user runs the program like this:
//
// go run main.go /sbin
//
// It should print this:
//
// #2 : "/sbin"
// ---------------------------------------------------------
// ---------------------------------------------------------
// BONUS EXERCISE
// Make your program cross platform. So, it can search
// the path environment variable when you run it on
// a Windows or on a Mac (OS X) or on a Linux.
//
// BONUS EXERCISE #2
// Also find the directories for the directories that
// contains the searched query.
//
// And let it match in a case-insensitive manner. See the examples.
//
// EXAMPLE:
// Let's say:
// PATH="/usr/local/bin:/sbin:/Users/inanc/go/bin"
//
// So, if the user runs the program like this:
// go run main.go bin
//
// It should print this:
// #1 : "/usr/local/bin"
// #2 : "/sbin"
// #3 : "/Users/inanc/go/bin"
//
// Or like this (case insensitive):
// go run main.go Us
//
// Output:
// #1 : "/usr/local/bin"
// #2 : "/Users/inanc/go/bin"
