For those that need it, there's a tac(1) implementation at I'll append the manpage below.
If enough people want this i guess it can be (re)considered for putting 
into NetBSD.

TAC(1)                  NetBSD General Commands Manual                  TAC(1)

      tac -- concatenate and print lines of files in reverse order

      tac [file ...]

      The tac utility reads the named files sequentially, and writes their
      lines to the standard output in reverse order.  First all lines of the
      first file are printed, then the next files are handled.  If no filename
      is given, or if - is given as filename, tac will read from standard

      cat(1), sed(1)

      A tac utility first appeared in NetBSD 5.  The implementation based on
      sed(1) was done by Antti Kantee <>, this manpage was
      written by Hubert Feyrer <>.
