Add Tail implementaiton #153

mike-ward · 2024-06-01T13:05:11Z

Tail implementation

uses 4K buffers for read/write operations. Handles large files easily.
-f option tracks by name, not descriptor. GNU uses descriptors but it really complicates things for little gain (imo)
uses ps to track PID's. May not work on Windows although most developers probably have it installed because tasklist is a GUI

Looks like you have fmt changes in here as well. It would be better to separate those to a different PR.

oops, probably fat fingered something. will fix.
