Two script files I wrote to help automate my usage of mfakto.

mfaktocmd.sh

#!/bin/sh

# Requires:
#     - entr
#     - tmux
#     - mfloop
#     - mfloop-runner.sh

mfakto and mfloop.py helper script written by Aurorans Solis
Options:
    start-fetch
        starts entr process watching worktodo.txt and runs mfloop with a
        timeout of 0 every time the file is edited

    start
        starts a tmux session running mfakto and uses entr to watch
        worktodo.txt, running mfloop with a timeout of 0 every time the file
        is edited by mfakto to fetch more work

    stop-fetch
        kills the entr process running mfloop so no more work is fetched

    stop
        stops entr, the tmux session, and mfakto

    status NUM_LINES
        displays the last NUM_LINES lines of output in the tmux session

    help
        prints this message
