Generate an unique id ... in python or bash or anything
Example python:
import id
new_unique_id = id.id()
Example bash:
# mkdir id_fs
# ./id_fs.py id_fs
# cat id_fs/id
Run tests:
./test_id.py
Optional - to run the id_fs
pip install --user fuse-python
Check id.py for more the implementation

It's harder to measure a clash here but it is always better to use this version, and later in post, I will explain why.
