No I'm running Linux tail, as it comes with Slackware, Redhat,
mandrake, SuSE, etc. Did you deliberately install UNIX tail on your
Linux system? And if so why doesn't the -NNNb option work to your
satisfaction?

yes, typo, that's 1998. But you knew that, since it's in the build
date of my original post:
Linux newsutil1 2.1.131 #4 SMP Thu Dec 10 10:59:04 EST 1998 i686 unknown

No, I'm running whatever tail comes with all the distributions I use
from choice or necessity. That's why I tried several machines of various
flavors, to see if the tail I used was something recent.
I really think you have some damaged version, the -b is flagged as
"tail: b: invalid suffix character in obsolescent option" (means
becoming obsolete, I think it is). Both Solaris and AIX also accept byte
counts larger than 64k, so there's no obvious reason to use b other than
habit.
No, I don't know or claim POSIX says it's obsolete, but I haven't seen
anyone actually use it in at least the last eight years, any I'm sure I
haven't used it in longer than that.
Anyway, I think there's no problem with >64k in standard Linux
distributions. I don't know what you're running, but it's not a Linux
problem in popular distributions.
