Grep example wrong in lessons 07-find

[anenadic]

$ grep "FE" $(find .. -name '*.pdb')
../data/pdb/heme.pdb:ATOM     25 FE           1      -0.924   0.535  -0.518

The above piece of code in lesson 07 (finding things) of shell-novice (http://swcarpentry.github.io/shell-novice/07-find/) does not work as there is no data file heme.pdb in the molecules directory. It also searched in the .. (parent) of the current directory instead of ../molecules.

Hi, I just downloaded the shell-novice-data.zip file from here. It seems that under the previous directory of the 'writing' directory, there is a 'data' directory (different from the data dir within the 'writing' dir), and within this 'data' directory, there is a 'pdb' dir, and within this dir a 'heme.pdb' file. So I think this example seems correct.

Closing as part of old issue cleanup. If there is still appetite for this change, we can reopen.
