📄 cp – Copy Files and Directories

✅ Syntax:

cp [options] source destination

📌 Description:

Copies files or directories from one location to another.

🧪 Examples:

cp file1.txt file2.txt               # Copy file1.txt to file2.txt
cp file1.txt /home/user/docs/        # Copy to another directory
cp -r myfolder/ /backup/folder/      # Recursively copy a directory
cp -u file.txt /target/              # Copy only if the file is newer

🛠️ Common Options:

Option	Meaning
-r	Recursively copy directories
-u	Copy only when the source is newer
-v	Verbose mode – show what’s happening
-i	Interactive – prompt before overwriting

🚚 mv – Move or Rename Files

✅ Syntax:

mv [options] source destination

📌 Description:

Moves files from one location to another. Also used to rename files or directories.

🧪 Examples:

mv oldname.txt newname.txt           # Rename file
mv file.txt /home/user/docs/         # Move to another directory
mv *.log /var/logs/archive/          # Move multiple files using wildcards
mv -i config.conf config.old         # Interactive rename

🛠️ Common Options:

Option	Meaning
-i	Prompt before overwrite
-v	Show each move step
-n	Do not overwrite any existing file

---

❌ rm – Remove/Delete Files and Directories

✅ Syntax:

rm [options] target

📌 Description:

Deletes files or directories permanently.

🧪 Examples:

rm file.txt                          # Delete a single file
rm -i important.txt                  # Confirm before deleting
rm *.bak                             # Delete all .bak files
rm -r myfolder/                      # Recursively delete a folder
rm -rf /tmp/test/                    # Forcefully remove without prompts

⚠️ Warning:

• Files deleted with rm do not go to Trash/Recycle Bin
• Use -i for interactive confirmation to avoid mistakes

🛠️ Common Options:

Option	Meaning
-r	Recursive deletion (for folders)
-f	Force deletion without prompts
-i	Interactive – ask before deletion

🔐 Best Practices for File Management

• 🛡️ Always use -i (interactive mode) when deleting or overwriting files.
• 🧪 Test with ls before applying destructive rm or mv commands.
• 📦 Use cp to backup files before editing or moving them.
• 🗂️ Use wildcards (*.log, file[1-3].txt) carefully to match multiple files.

📌 Summary – Recap & Next Steps

Efficient file management in Linux/Unix saves time and prevents costly mistakes. Mastering cp, mv, and rm ensures you can organize directories, migrate data, and clean up systems confidently.

🔍 Key Takeaways:

• cp copies files or directories and supports recursive and safe options.
• mv moves or renames files, with overwrite protections like -i or -n.
• rm deletes files permanently, so always use it with care.
• Interactive flags like -i help prevent accidental data loss.
