I'm try to figure it out but it don't get it. I have made a test, let's say that the the salt is "md5" and the text is "function", I just create the hash for "md5function" and put it in a test.txt file, then I create a second file with the text "function" and I call it pass.txt.
Now I want to find the "md5" salt and I use the following command:

hashcat -m 10 -a 3 -e pass.txt test.txt ?a?a?a

But it doesn't find it, what is wrong?

Code:

Added hashes from file test.txt: 1 (1 salts)
Activating quick-digest mode for single-hash
