manual_process

#!/usr/bin/env bash

#USAGE:  manual_process list-of-unmoved_files-filename
# The command displays available info on each recording in the list, giving
# you the possibility, after each recording, to enter a correct subtitle.
# Typically, the process involves copy-pasting the Description field to
# your favourite web search engine to determine the correct episode, then,
# assuming you find it, entering 'y', and entering that episode-subtitle
# back into the terminal and pressing <enter> to initiate processing of
# the recording.
#
#DESCRIPTION:
# This script provides an interactive mechanism to reprocess recordings
# that myth2kodi failed to processes automagically.
# Given a file containing a list of unmoved files (full-path), prints the 
# recording information to stderr (using: 'myth2kodi --recording-info'),
# then provides the option of inputting an appropriate subtitle, then uses
# that subtitle to call myth2kodi. Any process calls to myth2kodi are
# appended to a file named ./manual_moves.txt.
