TF includes a simple command line interface which is similar to the Linux or DOS/PowerShell prompt. You can cp or mv files, you can cat them or less them, and you can run a dir or a grep.
You can find it at https://github.com/patbeirne/tf
Here's a sample session:
There is also a sed command, which allows you to edit files inline. It's not an interactive editor, but it's handing for changing a constant or two in your .py code.

This project is 100% upython code, and lives in two files: tf.py and tf_extend.py. The module is written such that you can extract just the file_copy, file_grep and file_sed functions if that's all you need.
It's still early days in this project, so I'm open to suggestions:
- other command line options or changes in syntax
- would it be useful to pipe grep output to a file?
I find this module handy for visualizing the contents of the flash file system, cleaning up unused files and making backups of versions before trying changes.
If you do get as far as checking this out, scroll to the bottom of the README and look for 'extensions' where I put in some fun extra tools.
