Day 17 – Exploring the Command Line Further

Today marked Day 17 of my internship at Cudose Creative Agency, and we went deeper into the world of the command line interface (CLI). The more I use it, the more I understand why developers rely on it — it’s fast, direct, and very powerful once you know the right commands.

Working with Drives

We started by exploring drives from the command line. Instead of clicking through folders, we navigated between different drives using commands. This approach makes it clear how storage is structured and gives more precise control when working with files.

Changing Terminal Colours

Another interesting part of the day was learning how to change colours in the terminal. While this might seem like just a cosmetic feature, it helps with visibility and organization. For example, different colours can highlight errors, outputs, or even just make the workspace more comfortable for long sessions.

Delete vs RM Command

We also discussed the difference between deleting files in a GUI and using the rm command in the CLI:

In a graphical interface, deleted files often go to the Recycle Bin/Trash, where they can be recovered.

With rm, however, the deletion is permanent — the file doesn’t pass through any “safety net.”

This makes the CLI extremely efficient, but also unforgiving. It was a reminder that precision and caution are essential when running commands.

Copying and Moving Files

Finally, we worked with commands like cp (copy) and mv (move). These are fundamental for file management. Instead of dragging and dropping files, a single line can handle the task, making it much quicker — especially when working with multiple files or remote systems.

Reflection

Day 17 reinforced the idea that the command line is more than just typing text — it’s about understanding how the system works at a deeper level. Each command is like a direct instruction to the computer, and mastering them gradually builds confidence and efficiency.

I’m looking forward to exploring even more advanced commands as the journey continues.
