Count number of lines for each PDF in a folder

This is just a note about a script which may be useful to you. This one calculates the number of lines per PDF and prints the final count.

import sys

import fnmatch

import os

matches = []

for root, dirnames, filenames in os.walk(sys.argv[1]):

   for filename in fnmatch.filter(filenames, '*.pdf'):

       matches.append(os.path.join(root, filename))

count = 0

for mat in matches:

   if not mat.lower().endswith("pdf"): continue

   cmd = "pdftk " + mat +  " dump_data | grep NumberOfPages > pn.log"

   os.system(cmd)

   try:

     f = open("pn.log")

     l = f.read().strip().split(":")[1].strip()

     f.close()

     print(mat + "," + l)

     count = int(l) + count

   except:

     continue

print(count)

Have a great weekend ! :)
