Download/Print Version: Day 1: Puppy Linux Mastery Guide PDF

Introduction: Why Puppy Linux?

Puppy Linux is not just another Linux distribution—it’s a philosophy. Designed to run entirely in RAM, it’s incredibly fast, requires minimal resources, and can revive old hardware that other operating systems have left behind. Today, you’ll learn why Puppy is the perfect introduction to Linux fundamentals and system efficiency.

What Makes Puppy Unique:

Runs completely in RAM (typically uses 300-500MB)
Boots in 30-60 seconds even on ancient hardware
Can run from CD/DVD/USB without hard drive
Includes everything needed for daily computing in ~400MB
Perfect for understanding Linux basics without bloat
Saves state on shutdown (preserving your changes)

Today’s Learning Goals:

Master Puppy’s unique save file system
Understand RAM-based computing advantages
Navigate the lightweight desktop environment
Learn essential Linux commands in a forgiving environment
Configure and customize a minimal system
Rescue and recover data from other systems

Time Required: 6-8 hours (with breaks)

Morning Session (8:00 AM - 12:00 PM)

Hour 1: First Boot and Initial Setup (8:00 - 9:00 AM)

Boot Puppy Linux

Select Puppy Linux from Ventoy menu
Choose boot option: “puppy (First boot)” or similar
Wait for desktop to load (notice the speed!)

What’s Happening Behind the Scenes:

Puppy is decompressing itself into RAM
The entire operating system fits in memory
Your hard drive isn’t being touched yet
This is why it’s so fast—everything runs from RAM

Initial Configuration Wizard

Step 1: Keyboard Layout

Select your keyboard layout (typically US English)
Test it by typing in the text field
Why this matters: Linux uses different keyboard mappings; setting this correctly prevents frustration

Step 2: Time Zone Setup

Select your geographic location
Choose your specific time zone
Why this matters: Affects file timestamps, system logs, and scheduled tasks

Step 3: Desktop Resolution

Puppy will attempt auto-detection
Adjust if needed through the wizard
Why this matters: Running at native resolution improves clarity and performance

Understanding the Desktop Environment

Take 15 minutes to explore:

The Desktop Layout:

Desktop icons (typically: drive icons, home, trash)
Taskbar at bottom (or top, depending on Puppy version)
System tray with network, volume, battery indicators
Menu button (usually bottom-left)

Key Desktop Icons:

home - Your personal files directory
tmp - Temporary files (cleared on reboot)
Drive icons (sda1, sdb1, etc.) - Your computer’s storage devices

The Puppy Menu System:

Click the menu button (may be labeled “Menu” or show Puppy logo)
Notice the organization: Desktop, System, Utilities, Filesystem, etc.
This is different from Windows/Mac: Linux organizes by function, not application name

Exercise 1: Desktop Familiarization (15 minutes)

Right-click on desktop → observe context menu
Click each drive icon → notice they “mount” when clicked
Open “home” → this is your personal space
Open “tmp” → understand temporary storage
Explore menu categories without launching programs yet

Why This Matters: Puppy’s interface is intentionally simple. Understanding this layout teaches you fundamental Linux concepts (mounting, home directories, file hierarchies) without overwhelming complexity.

Hour 2: The Save File System (9:00 - 10:00 AM)

This is Puppy’s most important and unique feature. Master this, and you understand what makes Puppy special.

Understanding Puppy’s Persistence Model

The Concept:

Puppy runs entirely in RAM (volatile memory)
When you shutdown, RAM is erased
A “save file” preserves your changes between sessions
This save file can be on USB, hard drive, or other media

Why This Design?

Speed: RAM is 100x faster than even SSD storage
Safety: Your actual disk isn’t being constantly written to
Flexibility: Can run from read-only media (CD/DVD)
Recovery: Easy to start fresh if something breaks

Creating Your First Save File

You’ll be prompted on first shutdown, but let’s understand the options now:

Access the Save File Creator:
- Menu → System → Puppy Event Manager
- Or wait until shutdown (it will prompt automatically)
Choose Save File Location:
- Your USB drive (recommended for portability)
- Internal hard drive (if you have one)
- External drive
Select Save File Type:
- Normal save file - Single file containing all changes (recommended)
- Save folder - Directory with your changes (faster but less portable)
- Multisession CD/DVD - For optical media (not applicable here)
Set Save File Size:
- Minimum: 512MB (adequate for basic use)
- Recommended: 2048MB (2GB) for comfortable use
- Maximum: Depends on available space
- Our recommendation: 2GB to start

Exercise 2: Save File Strategy (20 minutes)

Let’s test the save system:

Create a test file:
- Open the file manager (desktop → “home” icon)
- Right-click in empty space → Create New → Text file
- Name it “day1_test.txt”
- Double-click to open, type: “Testing Puppy save system”
- Save and close
Change desktop appearance:
- Right-click desktop → Desktop → Set desktop background
- Choose a different wallpaper
- Apply changes
Install a program:
- Menu → Setup → Puppy Package Manager
- Search for “htop” (system monitor)
- Click “htop” in results
- Click “Do it” to install
- Close package manager
Make a system change:
- Menu → Desktop → Set default applications
- Look around (don’t change anything critical yet)
- Close

Now, let’s save and reboot:

Menu → Shutdown → Reboot
Choose “Save to file” when prompted
Select location: Your USB drive
Name: “puppysave” (or similar)
Size: 2048MB
Click “OK” and wait for creation
Allow system to reboot

After Reboot - Verify Persistence:

Is your test file still in home directory?
Is the wallpaper the same?
Check if htop installed: Menu → System → Htop
All should be preserved!

Understanding What Happened:

During shutdown, Puppy copied changed files from RAM to save file
Save file was stored on your USB drive
On reboot, Puppy loaded base system + your save file
All customizations restored from save file

Why This Is Powerful:

Your base system stays clean and pristine
Can delete save file anytime to start fresh
Multiple save files = multiple “profiles”
Corrupt save file? Boot fresh and create new one

Now that you understand persistence, let’s explore Puppy’s file system.

Understanding Linux File Hierarchy

The Root Directory (/): Unlike Windows (C:\, D:), Linux has one root: /

Key Directories You’ll Use:

/root - Your home directory (confusing name, but you’re the “root” user in Puppy)
/tmp - Temporary files (cleared on reboot)
/mnt - Where drives “mount” (become accessible)
/usr - User programs and applications
/etc - System configuration files
/opt - Optional/additional software

Exercise 3: File System Explorer (30 minutes)

Part A: ROX-Filer Basics

Puppy uses ROX-Filer as its file manager. Let’s master it:

Open ROX-Filer:
- Click “home” icon on desktop
- Or Menu → Filesystem → Root directory (to see everything)
Navigation Techniques:
- Single-click folders to open
- Back button to go up one level
- Path bar at top shows current location
- Click path components to jump to that location
View Modes:
- Menu bar → Display → Large Icons
- Menu bar → Display → Small Icons
- Menu bar → Display → List View
- Try each: Notice information displayed
Showing Hidden Files:
- Menu bar → Display → Show Hidden
- Notice files starting with “.” appear
- Why hidden? Usually configuration files you rarely need

Part B: File Operations Practice

Create a practice directory structure:

In home directory (/root):
- Right-click empty space → New Directory
- Name it “linux_practice”
- Enter the directory
Create subdirectories:
- Create: “documents”, “scripts”, “downloads”, “temp”
- This mimics a typical user directory structure
Create sample files:
- In documents: Right-click → Create → Text file → “notes.txt”
- In scripts: Create “test.sh”
- Practice creating several files
File Operations:
- Copy: Right-click file → Copy, navigate elsewhere, right-click → Paste
- Move: Drag and drop between folders
- Rename: Right-click → Rename
- Delete: Right-click → Delete (goes to trash)
- Trash location: /root/.trash
Multiple Selection:
- Hold Ctrl and click files to select multiple
- Right-click any selected file for batch operations

Part C: Understanding Permissions

This is crucial Linux knowledge:

Right-click any file → Properties
Notice Permissions tab:
- Owner: Who owns the file (you’re “root”)
- Group: Group ownership
- Others: Everyone else
Permission Types:
- Read (r): Can view file contents
- Write (w): Can modify file
- Execute (x): Can run as program
Understanding the Display:
- Example: “rwxr-xr-x”
- First three: Owner permissions (rwx = read, write, execute)
- Second three: Group permissions (r-x = read, execute only)
- Last three: Other permissions (r-x = read, execute only)

Exercise: Make a Script Executable

In your “scripts” folder, create “hello.sh”
Open it in a text editor

Type:

#!/bin/bash
echo "Hello from Puppy Linux!"

Save and close
Right-click → Properties → Permissions
Check “Execute” boxes
Double-click the file → Choose “Execute in Terminal”
See your message!

Why This Matters: Linux security is based on permissions. Understanding this now prevents confusion later when scripts won’t run or files won’t open.

Hour 4: Essential Applications and Tools (11:00 AM - 12:00 PM)

Puppy includes surprisingly complete software. Let’s explore what’s available and learn the philosophy behind it.

Puppy’s Software Philosophy

The Principle: Include one excellent tool for each task, not twenty mediocre ones.

Compare to Full Linux Distros:

Create a document with:
- Title: “My Puppy Linux System”
- Section 1: “Hardware Information”
  - (We’ll fill this in next section)
- Section 2: “Installed Software”
  - List programs you’ve noticed
- Section 3: “Custom Configurations”
  - Note changes you’ve made
- Section 4: “Learning Notes”
  - Things you’ve discovered today
Save as “system_documentation.txt” in your documents folder
Why This Matters:
- Good habit: Document your system
- Later, you’ll add technical details
- Useful reference when troubleshooting

- Location: /root/documents

Why This Skill Matters:

Documentation requires screenshots
Troubleshooting: Share what you see
Create tutorials for others

Lunch Break (12:00 PM - 1:00 PM)

Take a real break! Step away from the computer.

Reflection Questions While Eating:

How does Puppy’s speed compare to your regular OS?
What surprised you about the save file system?
Which applications seem most useful?
What feels different from Windows/Mac?

Afternoon Session (1:00 PM - 5:00 PM)

Hour 5: Command Line Fundamentals (1:00 - 2:00 PM)

The terminal is where Linux’s true power lives. Puppy is the perfect place to learn because mistakes are easily fixed.

Opening the Terminal

Multiple Ways:

Desktop → Terminal icon (if present)
Menu → Utility → Terminal
Right-click desktop → Window → Terminal here

What You See:

root@puppypc:~#

Breaking This Down:

root: Your username (Puppy logs you in as administrator)
@puppypc: Your computer name
~: Current directory (~ means home directory)
#: Prompt symbol (# means root/admin, $ means regular user)

Command: pwd (Print Working Directory)

pwd

Shows: Your current location in file system
Example output: /root
Why useful: Know where you are before acting

Command: ls (List)

ls

Shows: Files and directories in current location
Common options:
- ls -l - Long format (shows permissions, size, date)
- ls -a - Show all (including hidden files)
- ls -lh - Human-readable sizes (KB, MB, GB)
- ls -lt - Sort by modification time

Try It:

ls
ls -l
ls -lh
ls -a
ls -lah

Notice: Different information displayed
Hidden files: Start with “.”

Command: cd (Change Directory)

cd /usr
pwd
ls

Result: You’re now in /usr directory
Return home: cd or cd ~
Go up one level: cd ..
Go to root: cd /

Exercise 7: Navigate Your File System (15 minutes)

Complete this navigation challenge:

# Start at home
cd ~
pwd

# Go to your practice directory
cd linux_practice
pwd
ls

# Go into documents
cd documents
ls

# Go up one level
cd ..
pwd

# Go to system directory
cd /etc
ls
# Notice system configuration files

# Return home
cd ~
pwd

Pro Tips:

Tab completion: Type cd doc then press Tab - it completes to documents
Previous directory: cd - returns to last location
Path shortcuts:
- ~ = home directory
- . = current directory
- .. = parent directory

Essential Commands - Part 2: File Operations

Command: cat (Concatenate/Display File)

cat notes.txt

Shows: Entire file contents in terminal
Use case: Quick viewing of small files

Command: less (Page Through File)

less notes.txt

Shows: One page at a time
Controls:
- Space: Next page
- b: Previous page
- /search_term: Search in file
- q: Quit
Use case: Reading longer files

Command: cp (Copy)

cp source.txt destination.txt
cp file.txt /tmp/

Syntax: cp source destination
Copy directory: cp -r folder_name /tmp/
- -r means recursive (include contents)

Command: mv (Move/Rename)

mv oldname.txt newname.txt
mv file.txt /tmp/

Dual purpose: Rename OR move
No separate rename command in Linux

Command: rm (Remove)

rm file.txt
rm -r folder_name

WARNING: No trash bin, deletion is permanent!
Use with caution
For directories: Must use -r flag

Exercise 8: File Manipulation Practice (20 minutes)

Create and manipulate files from terminal:

# Go to practice area
cd ~/linux_practice/temp

# Create empty files
touch file1.txt file2.txt file3.txt
ls

# Add content to file
echo "This is a test" > file1.txt
cat file1.txt

# Append more content
echo "Second line" >> file1.txt
cat file1.txt

# Copy file
cp file1.txt file1_backup.txt
ls

# Rename file
mv file2.txt file2_renamed.txt
ls

# Create directory
mkdir test_folder
ls

# Copy file into directory
cp file1.txt test_folder/
ls test_folder/

# Remove file
rm file3.txt
ls

# Try to remove directory
rm test_folder
# Error! Directory not empty

# Remove directory and contents
rm -r test_folder
ls

Understanding Operators:

> - Redirect output to file (overwrites)
>> - Append output to file
| - Pipe output to another command

System Information Commands

Command: free (Memory Usage)

free -h

Shows: RAM and swap usage
-h = human readable format
Notice: How much is used? (Should be minimal in Puppy!)

Command: df (Disk Free)

df -h

Shows: Disk space on all mounted drives
See your save file size

Command: uname (System Information)

uname -a

Shows: Kernel version, architecture, hostname

Command: ps (Process Status)

ps aux

Shows: All running processes
Columns:

df -h >> system_info.txt

# View your report
cat system_info.txt

What You Learned:

$() runs command and uses output
Creating reports from command line
Gathering system diagnostics

Hour 6: Package Management and Software Installation (2:00 - 3:00 PM)

Puppy has a unique package management system. Understanding it teaches you about Linux software distribution.

Understanding Puppy Package Manager

Key Concepts:

Packages: Software bundled with dependencies
Repositories: Online storage of packages
Dependencies: Other software required for a package to work
PET packages: Puppy’s native package format
SFS files: Squashed File Systems (compressed bundles)

Using Puppy Package Manager

Open Package Manager:

Menu → Setup → Puppy Package Manager
Or Menu → Setup → PPM

Interface Overview:

Search bar: Find packages by name
Categories: Browse by type (Desktop, Document, Network, etc.)
Package list: Available software
Details pane: Information about selected package
Download/Install button: Usually says “Do it” or similar

Exercise 10: Installing Useful Tools (25 minutes)

Let’s install some practical software:

Tool 1: Midnight Commander (File Manager)

Search for “mc” in package manager
Select “mc” (Midnight Commander)
Read description: Text-based file manager
Click “Do it” to install
Wait for download and installation

Launch it:

mc

What is this? Dual-pane file manager in terminal
Navigation:
- Arrow keys to move
- Enter to open folders
- Tab to switch panes

Why useful? Fast file management without GUI

Tool 2: Wget (Download Tool)

Often pre-installed, but let’s verify:

Search for “wget” in package manager
If not installed, install it
If already installed, you’ll see “already installed”

Test wget:

cd ~/downloads
wget http://www.kernel.org/pub/linux/kernel/v1.0/linux-1.0.tar.gz
ls -lh
# Downloaded the original Linux kernel source!

Tool 3: Nano (Text Editor)

Simpler than Geany for quick edits:

Check if installed: which nano
If not found, install from package manager
Test it:
```
nano test.txt
```
Controls:
- Type normally
- Ctrl+O to save
- Ctrl+X to exit
- Bottom shows commands (^ means Ctrl)

Tool 4: Git (Version Control)

If you plan to code:

Search for “git” in package manager
Install git-core or similar
Test: git --version

Why Learn Package Management?

Every Linux distro has a package manager
Understanding this helps with any Linux system
Safer than downloading random executables
Automatic dependency resolution

Understanding SFS Files

What are SFS files?

Squashed File System: Compressed read-only filesystem
Contains entire applications or libraries
Can be “loaded” without traditional installation
Saves space, easy to add/remove

Using SFS Files:

Access SFS Manager:
- Menu → Setup → SFS Manager
Loading an SFS:
- Browse to .sfs file
- Click “Load”
- Software becomes available immediately
- No permanent installation
Unloading SFS:
- Select loaded SFS
- Click “Unload”
- Software disappears

When to Use SFS:

Large software suites you use occasionally
Testing software without commitment
Running multiple versions of same program

Exercise 11: Explore Available SFS (15 minutes)

Visit puppylinux.com in browser
Navigate to Downloads → Additional SFS
Browse available SFS packages:
- Development tools

2. Memory Management:

Menu → System → Pmem (Puppy Memory Monitor)
Observe what’s using RAM
Close unnecessary programs

3. Swap Configuration:

# Check if swap is enabled
free -h

# If you need swap (unlikely in Puppy):
# Menu → System → GParted → Create swap partition

4. Create Efficiency Scripts:

Create a cleanup script:

cd ~/scripts
nano cleanup.sh

Add this content:

#!/bin/bash
# Cleanup script for Puppy Linux

echo "Starting cleanup..."

# Clear thumbnail cache
rm -rf ~/.thumbnails/*

# Clear trash
rm -rf ~/.trash/*

# Clear temp files
rm -rf /tmp/*

# Clear browser cache (adjust path for your browser)
rm -rf ~/.mozilla/firefox/*.default/cache/*

echo "Cleanup complete!"

Make it executable:

chmod +x cleanup.sh

Run it:

./cleanup.sh

Create a backup script:

nano backup.sh

Add:

#!/bin/bash
# Backup important files

BACKUP_DIR="/mnt/home/puppy_backups"
DATE=$(date +%Y%m%d)

mkdir -p $BACKUP_DIR

# Backup documents
tar -czf $BACKUP_DIR/documents_$DATE.tar.gz ~/documents/

# Backup scripts
tar -czf $BACKUP_DIR/scripts_$DATE.tar.gz ~/scripts/

echo "Backup complete: $BACKUP_DIR"

Make executable:

chmod +x backup.sh

Why This Matters:

Automation saves time
Regular maintenance prevents issues
Scripts are reusable across Linux systems

Hour 8: Advanced Topics and Real-World Use Cases (4:00 - 5:00 PM)

Now that you understand Puppy, let’s explore practical applications.

Use Case 1: System Recovery and Data Rescue

Puppy excels at rescuing data from broken systems.

Scenario: Your main computer won’t boot. How can Puppy help?

Exercise 14: Data Rescue Simulation (20 minutes)

Boot Puppy (you’re already here)
Mount the “broken” drive:
- Click drive icons on desktop
- They mount to /mnt/
- Example: /mnt/sda1

Navigate to data:

cd /mnt/sda1/
ls
# You'd see the other OS's file structure

Copy important files:

# Copy to USB drive
cp -r /mnt/sda1/Users/YourName/Documents /mnt/sdb1/rescue/
   
# Or create compressed backup
cd /mnt/sda1/Users/YourName/
tar -czf /mnt/sdb1/documents_backup.tar.gz Documents/

Verify the copy:

ls -lh /mnt/sdb1/rescue/
# Check file sizes match

Real-World Recovery Techniques:

Photo recovery: Use TestDisk (install from package manager)
Partition recovery: GParted (Menu → System → GParted)
Password reset: Use chroot to access other Linux systems
Windows data access: Puppy can read NTFS partitions

Exercise 15: Create a Rescue USB Toolkit (15 minutes)

Make Puppy your go-to rescue system:

Install recovery tools:

# From Package Manager:
# - testdisk (file recovery)
# - gparted (partition editor)
# - ddrescue (disk cloning)

Create a rescue scripts folder:

mkdir ~/rescue_scripts
cd ~/rescue_scripts

Create a mount helper script:

nano mount_all.sh

Add:

#!/bin/bash
# Mount all available partitions
   
echo "Mounting all partitions..."
   
for partition in /dev/sd[a-z][1-9]; do
    if [ -b "$partition" ]; then
        mount_point="/mnt/$(basename $partition)"
        mkdir -p $mount_point
        mount $partition $mount_point 2>/dev/null
        if [ $? -eq 0 ]; then
            echo "Mounted $partition to $mount_point"
        fi
    fi
done
   
echo "Done! Check /mnt/ for mounted drives"

Make executable:

chmod +x mount_all.sh

Create a data finder script:

nano find_documents.sh

Add:

#!/bin/bash
# Find common document locations
   
echo "Searching for documents..."
   
find /mnt -type f \( -name "*.pdf" -o -name "*.doc*" -o -name "*.xls*" -o -name "*.ppt*" \) 2>/dev/null | head -20
   
echo ""
echo "Searching for photos..."
find /mnt -type f \( -name "*.jpg" -o -name "*.jpeg" -o -name "*.png" \) 2>/dev/null | head -20

Make executable:

chmod +x find_documents.sh

Why This Use Case Matters:

Puppy can boot when other systems fail
Access data from any OS (Windows, Mac, Linux)
Small size means fast deployment
No installation required - just boot and rescue

Use Case 2: Portable Computing Environment

Scenario: You need a consistent computing environment across multiple computers.

Exercise 16: Configure Portable Workspace (15 minutes)

Essential portable applications:
- Web browser with bookmark sync
- Text editor with your configurations
- SSH client for remote access
- Cloud storage sync tools

Create portable config backup:

cd ~
mkdir portable_configs
   
# Copy important configs
cp .bashrc portable_configs/
cp -r .config portable_configs/
cp -r scripts portable_configs/
   
# Create restore script
nano portable_configs/restore.sh

Add:

#!/bin/bash
# Restore portable configurations
   
cp portable_configs/.bashrc ~/
cp -r portable_configs/.config ~/
cp -r portable_configs/scripts ~/
   
echo "Configurations restored!"

Sync your save file:
- Keep your Puppy save file on USB
- Boot any computer with same environment
- All settings and files travel with you

Benefits:

Same desktop on any computer
Your tools always available
Privacy - no traces left on host computer
Educational - learn on different hardware

Use Case 3: Testing and Learning Environment

Scenario: Learn Linux without risking your main system.

Exercise 17: Safe Experimentation Zone (10 minutes)

Create experimental save files:

# Can have multiple save files for different purposes:
# - puppysave_learning.2fs (for tutorials)
# - puppysave_coding.2fs (for development)
# - puppysave_rescue.2fs (for recovery tools)

Practice “dangerous” commands safely:

# These are safe in Puppy because of RAM operation:
   
# Explore system files
cd /etc
cat /etc/passwd  # User database
cat /etc/fstab   # File system table
   
# Modify configs (only affects RAM until saved)
nano /etc/hosts  # Network hosts file
   
# If you break something?
# Just reboot without saving!

Learn scripting without fear:

cd ~/scripts
nano experiment.sh

Try various commands:

#!/bin/bash
   
# Loop example
for i in {1..5}; do
    echo "Count: $i"
done
   
# Conditional example
if [ -f "test.txt" ]; then
    echo "File exists"
else
    echo "File not found"
    touch test.txt
fi
   
# Function example
greet() {
    echo "Hello, $1!"
}
   
greet "Puppy Linux User"

Learning Advantages:

Mistakes don’t persist (unless you save)
Fast reboots for fresh starts
Understand system internals hands-on
Build confidence with Linux

Evening Session (5:00 PM - 6:00 PM)

Final Hour: Review and Next Steps

Comprehensive System Check

Exercise 18: System Mastery Verification (20 minutes)

pwd

Create a project structure:

cd ~
mkdir my_first_project
cd my_first_project
mkdir src docs tests scripts
touch README.md
echo "# My First Linux Project" > README.md
cat README.md

Write a practical script:

cd scripts
nano system_report.sh

Add:

#!/bin/bash
# Complete System Report
   
REPORT_FILE=~/documents/system_report_$(date +%Y%m%d_%H%M%S).txt
   
echo "=== PUPPY LINUX SYSTEM REPORT ===" > $REPORT_FILE
