gistfile1.txt

#!/bin/sh
# This script opens the last screenshot taken and runs OCR on it to extract text.
# It used tesseract (see https://tesseract-ocr.github.io/)

# Configured with Ubuntu's Screenshots folder. Change to your own.
SCREENSHOTS_DIR=$HOME/Pictures/Screenshots

# Create the folder to put the output into, if needed
mkdir -p $SCREENSHOTS_DIR/ocr_output

# Get the last screenshot taken
LAST_FILE="$SCREENSHOTS_DIR/$(ls --color=never -t $SCREENSHOTS_DIR | grep ".png" | head -n 1)"

# Run OCR on the screenshot
OUTPUT_FILE_WITHOUT_EXT="$SCREENSHOTS_DIR/ocr_output"
OUTPUT_FILE="${OUTPUT_FILE_WITHOUT_EXT}.txt"
tesseract "$LAST_FILE" "$OUTPUT_FILE_WITHOUT_EXT"

# Open the OCR output
echo ""
echo "==============================================="
echo "Extracted text from screenshot:"
echo "==============================================="
echo ""
cat "$OUTPUT_FILE"
# xdg-open "$OUTPUT_FILE"

# Optionally, copy text to clipboard (requires xclip to be installed)
# xclip -selection clipboard "$OUTPUT_FILE"
