PDF To Report Workflow

# Get full PDF info
pdfinfo document.pdf

# Get only page count
pdfinfo document.pdf | grep Pages

# Extract page count as a number
pdfinfo document.pdf | grep Pages | awk '{print $2}'

# Extract all text to stdout
pdftotext document.pdf -

# Extract text to a file
pdftotext document.pdf output.txt

# Extract text from specific page range
pdftotext -f 1 -l 3 document.pdf output.txt

# Preserve layout (rough formatting)
pdftotext -layout document.pdf output.txt

# Install if needed
apt-get install -y enscript ghostscript

# Convert text file to PDF
enscript -B -o output.ps input.txt && ps2pdf output.ps output.pdf

# One-liner
enscript -B input.txt -o - | ps2pdf - output.pdf

# Install if needed

# Convert HTML file to PDF
wkhtmltopdf input.html output.pdf

# Convert from stdin
echo "<html><body><h1>Report</h1></body></html>" | wkhtmltopdf - output.pdf

# With options for better quality
wkhtmltopdf --page-size A4 --margin-top 25mm input.html output.pdf

# Install if needed
apt-get install -y libreoffice-writer

# Convert to PDF (headless mode)
libreoffice --headless --convert-to pdf input.docx
libreoffice --headless --convert-to pdf input.odt
libreoffice --headless --convert-to pdf input.txt

# Install if needed

# Convert markdown to PDF
pandoc input.md -o output.pdf

# Convert text to PDF
pandoc input.txt -o output.pdf

# With custom template
pandoc input.md --template=template.tex -o output.pdf

# Install if needed
apt-get install -y pdftk

# Merge multiple PDFs
pdftk file1.pdf file2.pdf file3.pdf cat output merged.pdf

# Extract pages
pdftk input.pdf cat 1-3 output extracted.pdf
