Mastering File Management

Managing files is a core shell skill. This lesson covers the four essentials: mkdir, cp, mv, and rm — create, copy, move, delete.

Creating Folders with `mkdir`

mkdir (make directory) creates a new folder — just give it a name. Try making one called my_documents.

mkdir my_documents

Advanced `mkdir` Usage

Create several folders at once by listing names. Add -p to build nested directories, creating any missing parents along the way.

mkdir reports project/src/main -p

Copying Files with `cp`

cp (copy) duplicates a file: give it a source and a destination. Here we use touch to make a file first, then copy it.

touch notes.txt
cp notes.txt backup_notes.txt

Copying Folders with `cp -r`

To copy a whole folder, add -r (recursive) so cp grabs the directory and everything inside. Without it, folders are skipped.

mkdir data_folder
touch data_folder/file_a.txt
cp -r data_folder archived_data

Moving Files with `mv`

mv (move) relocates files or folders — like cut and paste. Point it at a source and a destination directory.

touch document.pdf
mkdir important_files
mv document.pdf important_files/

Renaming Files & Folders

Bonus: mv also renames. Move a file to the same place with a new name, and you’ve renamed it.

touch old_report.txt
mv old_report.txt new_report.txt

Deleting Files with `rm`

rm (remove) deletes files — permanently, with no trash to recover from. Always double-check what you’re removing.

touch unwanted.txt
rm unwanted.txt

Deleting Folders with `rm -r`

To delete a non-empty folder, add -r so rm clears the directory and its contents. Extreme caution — this is irreversible.

mkdir empty_folder
rm -r empty_folder

Quick Check: File Management

Imagine you have a file named draft.txt in your current directory. You want to create a new folder called final_docs and then move draft.txt into it, renaming it to final_report.txt in the process. Which sequence of commands would achieve this?

Lesson Summary

Great work! You’ve got file management down: mkdir to create, cp to copy, mv to move or rename, and rm to delete (with -r for folders).
