Each -e needs a following expression, so 'p' after it is
Kernel#p, however, -p doesn't take arguments so 'e' after it is
-e.

dumb me. all the time i thought the quotes were required for -e and
that a space should separate it fr the expression :))
so now even "ruby -pe0 *.txt" should work!

many thanks for the englightenment, nobu.
kind regards -botp
