|
|
// 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"
|
