How to implement line sorting, uniquifying and counting function in emacs? |

In shell you can do this:
cat file | sort | uniq -d | wc
to count the repeated lines. You can also do
cat file | sort | uniq -u | wc
to count the unique lines.
Sometimes I have to do this on windows platform where I do have emacs.
This means that I cannot escape to shell and that route is not available.
Lisp has sort-lines, but no uniq -u or uniq -d available. Also I do not
know the equivalent to wc.
This is where some help is requested. I think that this is not only a
problem of lisp programming, but also algorithms. Which group has this
kind of expertise?
Cheers!
