Anime CRC32 checksum in Linux

Posted by Taoufix on Aug 31st, 2007 in Computers, Media & Fun

Make sure you have python fchksum installed (for gentoo users : emerge dev-python/python-fchksum)

[python]#!/usr/bin/python
import fchksum

for file in sys.argv[1:]:
print fchksum.fcrc32t(file)[0], ” “, file[/python]

[shell]$ ./crc32sum.py [DB]_Naruto*
F71B0275 [DB]_Naruto_Shippuuden_025_F71B0275].avi
35057A9C [DB]_Naruto_Shippuuden_026_35057A9C].avi[/shell]

[Update 2008.11.05] Here’s a version which doesn’t need extra modules installation: animecheck.py

Thanks, had searched for some time.

I need to tell you, thought, that this script doesn’t work as it is, because of the quotes, that have been changed to non-ASCII characters…

@Franz: sorry, the post got messed up during the migration to wordpress. I uploaded an updated version of the script.

I improved it a little: http://pastebin.com/f6decf8fc
(Uses a regexp to find the CRC32 in the filename more reliably)

I have noticed that this script has some size limitations (it was about 1G for me).
I have found another program, cksfv, which can crc32 calculations.
It is designed to be used with a .sfv file, but if you just give it the file names, it will print the name and hash.

I’m sure it would not be very hard to write a bash script to handle the checking, and the colours.

(There is also bsdsfv, but cksfv seems better).
