Extra stuff is otput to stderr, you see it in terminal, but it isn't
subject to '>' redirection or `` capture.

Actually, you may do all in one script like this
#!/bin/sh
msnurl="https://www.livenewsmag.com/msnbc-news-live-stream/"
recdate=`date "+%Y%m%d-%H%M"`
m3u8url=`curl "https://www.livenewsmag.com/msnbc-news-live-stream/" |
grep -o -e "https://.\+m3u8" | head -n 1`
ffmpeg -referer $msnurl -i $m3u8url -c copy "msnbc-${recdate}.mp4"
