I know it absolutelly has nothing to do with databases or files in folders but
as we are talking about optimizing:
#!/bin/bash
CANDIDATES=(pix1.jpg pix2.jpg pix3.jpg)
for i in "${CANDIDATES[@]}"; do
MD5SUM=$(md5sum <(echo $i))
echo "$i ${MD5SUM% *}";
done
It's more than twice as fast than the previous sh script.
[ willing to learn mode, feel free to ignore this]
Anyway, about the the hashes and directories and so on... I assume we'd need a
hash table in our application, right?
Would we proceed as follows (correct me if I'm wrong please)?
1- m5sum the file we need
2- look for the first letter of the hash
3- get into the directory
4- now we look for our file
Is this right? I understand this would improve the searching of files when
there's a lot of them.
