"What's MultiTail? It's an ncurses utility that can display
multiple files using 'windows' (much like GNU Screen or Tmux) in a
terminal or at the console. It also supports color highlighting,
filtering and much more.
"To get MultiTail, head over to the download page or see if your
operating system already has packages. On Debian-based systems, you
should need to look for only the multitail package. The project
released an update (5.2.8) on April 14, so the most recent release
probably won't be in your upstream package repo just yet."
