Given encouragement to try tmux, here is what I’ve come up with as a “one-liner” (script) that does what I was originally looking for:

<span style="color:#323232;">#!/bin/sh
</span><span style="color:#323232;">
</span><span style="color:#323232;">tmux new-session -d -s split_screen_grep ; 
</span><span style="color:#323232;">  send-keys "/bin/sh -c '$1' | tee /tmp/split_screen_grep.txt" C-m ; 
</span><span style="color:#323232;">  split-window -h ; 
</span><span style="color:#323232;">  select-pane -t 1 ; 
</span><span style="color:#323232;">  send-keys "tail -f /tmp/split_screen_grep.txt | grep '$2'" C-m ;
</span><span style="color:#323232;">
</span><span style="color:#323232;">tmux attach-session -t split_screen_grep
</span>

I use it as follows, first arg is a command, second arg is a pattern to search for:

<span style="color:#323232;">$ ./split-grep "cat big_file.txt" "tmux"
</span>
