These are slightly wrong - the "grep :" will provide empty output when
applied just to the second field.  You meant something like:

fgrep : File.txt | cut -d: -f2 | fgrep -f - john.pot

BTW, it is fairly important to use fgrep (not grep).  Some hash
encodings contain dots and dollar signs, which are special to grep.

Anyway, all of these are just non-perfect hacks.  To get the job done in
a more correct manner, a custom script would need to be written or we
need to add functionality to JtR itself (another --show output format).
