Normalize a PATH-Style List

Introduction

A configuration export stores directory names on one colon-separated line and repeats some entries. A normalized list is easier to inspect and compare.

This challenge combines only text-processing commands already introduced: translate a delimiter, sort lines, remove adjacent duplicates, and save the result.

Create the Normalized Directory List

Current Situation

/home/labex/project/path-audit/configured-path.txt contains one colon-separated line. Some directory strings occur more than once.

Scope

• Convert each colon-separated entry into its own line.
• Sort the lines alphabetically.
• Keep each distinct directory string once.
• Save the result as path-directories.txt.

Your Goal

Create one sorted, duplicate-free directory list.

Acceptance Criteria

• path-directories.txt contains the four distinct source directory strings, one per line.
• The lines are alphabetically sorted.
• The source file remains unchanged.

Hints

Summary

You built one normalized list by combining delimiter translation, sorting, duplicate removal, and redirection.
