Hi Corona688,
That might be true in some implementations. (And the BSD based awk on MacOS Version 10.14.5 does work that way.) However, the description of the awk RS variable in the standards is:
Quote:
The first character of the string value of RS shall be the input record separator; a
<newline> by default. If RS contains more than one character, the results are
unspecified. If RS is null, then records are separated by sequences consisting of a
<newline> plus one or more blank lines, leading or trailing blank lines shall not
result in empty records at the beginning or end of the input, and a <newline> shall
always be a field separator, no matter what the value of FS is.
