[Guide] Universal Flash Notepad with Automatic History Cleanup (Zorin OS Lite)

AI-assisted tutorial, please verify critical steps

This guide explains how to set up an automated, ultra-lightweight Flash Notepad shortcut for Zorin OS 18 Lite (XFCE). It allows you to take timestamped notes instantly via a sleek graphical prompt without opening a heavy text editor.

To ensure total integration with your automated backups, the main script is stored inside the hidden .config directory, meaning it will be automatically backed up every week into your system architecture without any manual intervention.

🎯 Features

  • Instant Graphical Saisie: Uses a lightweight native XFCE dialog box (zenity) to capture your ideas in a split second.
  • Smart FIFO Retention: The script applies a strict rolling history log. It automatically limits the file to your 50 most recent notes (maximum 100 lines). When you type your 51st note, the oldest entry is cleanly removed from the top of the file, keeping your desktop file permanently light and readable.
  • Zero Performance Impact: The script reads and processes the small text file in less than 2 milliseconds before completely shutting down, requiring 0% CPU or RAM in background usage.

Step 1: Create the Notepad Script inside the Config Directory

Open your Terminal (Ctrl + Alt + T), copy-paste the following command block, and press Enter to generate the core script:

mkdir -p ~/.config
cat << 'EOF' > ~/.config/note_flash.sh
#!/bin/bash

FICHIER_NOTES="$HOME/Desktop/Notes_Rapides.txt"
FICHIER_TEMP="/tmp/notes_nettoyees.txt"

# 1. Graphical window prompt to capture the note
NOTE=$(zenity --entry --title="Flash Notepad" --text="Type your note below:")

# If the input field is empty or cancelled, exit cleanly
if [ -z "$NOTE" ]; then
    exit 0
fi

# 2. Append the new note at the bottom of the text file
DATE=$(date "+%m/%d/%Y at %H:%M")
echo "[$DATE] : $NOTE" >> "$FICHIER_NOTES"
echo "--------------------------------------------------" >> "$FICHIER_NOTES"

# 3. AUTOMATIC CLEANUP: Restrict history log to the last 50 entries
# In our structure, each note block takes exactly 2 lines.
# 50 notes x 2 lines = 100 maximum lines.
LIMITE_LIGNES=100

if [ -f "$FICHIER_NOTES" ]; then
    # Extracts only the X most recent lines and pipes them into a temp file
    tail -n "$LIMITE_LIGNES" "$FICHIER_NOTES" > "$FICHIER_TEMP"
    # Overwrites the old file with the cleaned temporary history
    mv "$FICHIER_TEMP" "$FICHIER_NOTES"
fi

# 4. Discrete system desktop notification
notify-send -i accessories-text-editor "Note Saved" "Added to Notes_Rapides.txt on your Desktop. Log capped at 50 notes."
EOF

Step 2: Make the Script Executable

Grant the system permission to run the newly created script file by executing this command:

chmod +x ~/.config/note_flash.sh

Step 3: Create the "Take a Note" Button on the Desktop

To access your notepad with a simple double-click without opening a black terminal window, generate the launcher file directly on your desktop by copying and pasting this block:

cat << 'EOF' > ~/Desktop/Take_Note.desktop
[Desktop Entry]
Version=1.0
Type=Application
Name=Take a Note
Comment=Instantly logs a timestamped note into a clean text file
Exec=bash -c "$HOME/.config/note_flash.sh"
Icon=accessories-text-editor
Terminal=false
Categories=Utility;
EOF
chmod +x ~/Desktop/Take_Note.desktop

🚀 How to Use It

Minimize your active windows and go to your Desktop. You will find a new notepad launcher called "Take a Note" with a classic notebook icon.

  1. Double-click it for the very first time. Zorin OS Lite will pop up a basic security warning: click "Mark Executable" to authorize the file permanently.
  2. Type your note inside the sleek entry field and press Enter.
  3. A text file named Notes_Rapides.txt will appear on your desktop. You can double-click it normally at any time to modify it or clear entries manually with the standard text editor (Mousepad).
