I don't seem to have "highlight" on my system.
That's because it is in ports rather than in base. (-:
* https://freshports.org/textproc/highlight/
* https://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/textproc/hi...
* http://ports.su/textproc/highlight
* https://ports.macports.org/port/highlight/
Why not just install `bat` at that point?
