Find old and large files in a directory tree. Write a function that traverses a user-given directory

Find old and large files in a directory tree.

Write a function that traverses a user-given directory tree
and returns a list of all files that are larger than X Mb and that have not
been accessed the last Y days, where X and Y are parameters to the function.
Include an option in this function that moves the files to a subdirectory trash
under /tmp (you need to create trash if it does not exist).

Hints: Use shutil.copy and os.remove to move the files (and
not os.rename, it will not work for moving files across different filesystems).
First build a list of all files to be removed.

Find old and large files in a directory tree.

Write a function that traverses a user-given directory tree
and returns a list of all files that are larger than X Mb and that have not
been accessed the last Y days, where X and Y are parameters to the function.
Include an option in this function that moves the files to a subdirectory trash
under /tmp (you need to create trash if it does not exist).

Hints: Use shutil.copy and os.remove to move the files (and
not os.rename, it will not work for moving files across different filesystems).
First build a list of all files to be removed. Thereafter, remove the files
physically.

To test the script, you can run a script fakefiletree.py (in
src/tools), which generates a directory tree (say) tmptree with files having
arbitrary age (up to one year) and arbitrary size between 5 Kb and 10 Mb:

fakefiletree.py tmptree

If you find that fakefiletree.py generates too many large
files, causing the disk to be filled up, you can take a copy of the script and
modify the arguments in the maketree function call. Remember to remove tmptree
when you have finished the testing.
