nice-rid — resolve subreddit names to Reddit/SocialGist t5_ ids (for the NICE pipeline config/pilot.yml)

nice-rid.sh

#!/usr/bin/env bash
#
# nice-rid — resolve subreddit names to their internal SocialGist/Reddit t5_ ids
#
# WHY: the 'nice' pipeline's config/pilot.yml needs, per subreddit, the Reddit
# "fullname" (t5_...), which SocialGist/BoardReader calls `filter_site_key`.
# Reddit blocks datacenter IPs on its .json API, so this must run from a normal
# machine (residential IP / logged-in browser session).
#
# USAGE:
#   bash nice-rid.sh                 # uses the built-in NICE subreddit list
#   bash nice-rid.sh ACL ORIF ...    # or pass your own names
#
# OUTPUT:
#   1. a human table:  subreddit  t5_id  subscribers
#   2. a ready-to-paste YAML block for config/pilot.yml
#
