Many files have text internally, and I am not sure there is a magic for plain text, so file might not be that useful. I actually wrote a pctbin C command to find out what percentage of characters were not in the common ASCII text file set: ' ' through '~', line feed, carriage return, form feed. The trick is figuring out what your professor defines as text!

You can find * -type f | xargs -n999 file and see all the types you have, and write a grep -E pattern that will select or deselect so only text types survive. You can use sed to remove the suffix of ": file type".

The permission are visible in find -ls or ls -l, and you can grep for them, too. Sorting by date is easy with ls -t, but ls has a file count limit. If you use the date, watch out for ls -l having a date-time form for one year and then a date-year form. I wrote a trivial C to take a stream of file name lines and spit them back out prefixed with the mtime.

Hope this helps!
