 #### Navigating the Unix File System
 Navigating the Unix file system is essential for efficiently managing files and directories within the operating system. As shown in **Figure 2**, he Unix file system sits within the Unix operating system (OS) and is structured as a hierarchical tree, starting from the root directory and branching out into subdirectories. Basic commands like `cd` (change directory), `ls` (list files) and `pwd` (print working directory) allow users to move through this structure, view contents and identify their current location. Understanding file paths (both absolute and relative) is crucial for accessing files accurately for a variety of analyses. Mastering these navigation skills streamlines data analyses and workflow development by laying the groundwork for utilising powerful bioinformatics tools.

 #### File Management
 File management in Unix is a critical skill for effectively organising and manipulating data within the operating system. Unix provides a variety of commands that facilitate the creation, deletion and modification of files and directories. Commands such as `mkdir` (make directory), `rm` (remove files), `cp` (copy files) and `mv` (move or rename files) empower users to maintain an orderly file structure, essential for handling large datasets commonly encountered in fields like bioinformatics.
