Make all markdown files in directory into PDFs

gistfile1.mak

# Produce PDFs from all Markdown files in a directory
# Lincoln Mullen | http://lincolnmullen.com | lincoln@lincolnmullen.com

# List files to be made by finding all *.md files and appending .pdf
PDFS := $(patsubst %.md,%.md.pdf,$(wildcard *.md))

# The all rule makes all the PDF files listed
all : $(PDFS)
                        
# This generic rule accepts PDF targets with corresponding Markdown 
# source, and makes them using pandoc
%.md.pdf : %.md
        pandoc $< -o $@

# Remove all PDF outputs
clean :
        rm $(PDFS)

# Remove all PDF outputs then build them again
rebuild : clean all

Exactly what I was looking for, and I learned a thing or two about makefiles too. Thanks!

Very useful, thank you.
