[kwlug-disc] Fwd: Regular Expression to Match Movie Titles and Year and Ignore the rest.

[John Driezen]

OK.  I managed to get a working python script to accomplish the intended 
task.  Here it is:

import os
import re

LOGFILE = "/home/john/logs/rename.log"
logfile = open(LOGFILE, 'w')

with os.scandir() as i:
     for entry in i:
         if entry.is_file():
             ## Use named groups for easy use of captured data:
             ## Also, put it all in one regex for easy positional 
grabbing of
             ## elements:
             ## Finally, wrapped for legibility in email, etc.:
             oldfile = entry.name
             print(oldfile)
             info = re.search(
                 "^"
                 + "(?P<title>.*)"                  # capture movie title
                 + "\.(?P<year>\d{4})\."      # capture year
                 + "(?P<res>\d+p)"              # capture resolution
                 + ".*\.(?P<ext>.*)"              # capture filename 
extension
                 + "$",
                 oldfile)
             title = info.group('title')
             movietitle = title.replace('.', ' ') # convert periods to 
spaces
             year = info.group('year')
             resolution = info.group('res')
             ext = info.group('ext')
             if (movietitle and year and resolution and ext): # do not 
write new filename if any values are None
                 newfile = movietitle+" ("+year+")-"+resolution+"."+ext
                 print (newfile)
                 #os.rename(oldfile, newfile)    # rename movie file
                 #os.chmod(newfile , 0o644)      # set permissions on 
movie file
                 log_message = oldfile + " renamed as " + newfile + "\n"
                 print (log_message)
                 logfile.write(log_message)

logfile.close()

Thank you to all for suggestions.
