I honestly use tac more then cat

I'm not sure I have ever used tac for real. Could you give an example?

Reading a log file from most recent entry for example

Cat *log|grep error|tac for example

Tail -500 log | tac

When you want to tail a file, but you want it in descending order and you’re not sure how much of it you want:

    tac file | less

I guess the difference is that I expect things to read top to bottom, so I'd do that as

  less foo.log
  G

Fair enough, if that’s how you want it to read. less on its own is certainly quite capable.

I'll just stick with tail -f until they implement tac -f

In my experience it's best to do

  cat file | tac

Why?

Moar cat!
