Hi!
According to XBD, 5 ("File Format Notation"), L3071:
’ ’ (An empty character position.)
Represents one or more <blank> characters
and XRAT, A.5 ("File Format Notation") agrees in L117453-117455,117456-117457:
Note that an empty character position in format represents
one or more <blank> characters on the output (not white space,
which can include <newline> characters).
The '∆' character is used when exactly one <space> is output.
So I think this is as-expected.
However, XCU, 3, cksum, L83395-83398 says:
STDOUT
For each file processed successfully,
the cksum utility shall write in the following format:
"%u %d %s\n", <checksum>, <# of octets>, <pathname>
If no file operand was specified,
the pathname and its leading <space> shall be omitted.
So: huh? What if you wanted to output:
%zu\t%zu\t%s\n
A strict reading would mean that the no-operand output should be
%zu\t%zu\t\n
(or, indeed %zu\t%zu\t %s\n -> %zu\t%zu\t\n, &c.)
but that's obviously wrong?
Is the standard's intent to require
"%u∆%d∆%s\n"
or should the section read something like
STDOUT
For each file processed successfully,
the cksum utility shall write in the following format,
if any file operands were specified:
"%u %d %s\n", <checksum>, <# of octets>, <pathname>
or if no file operand was specified:
"%u %d\n", <checksum>, <# of octets>
Line numbers from 202x/D2.1, also affects Issue 7.
(Also, if touching this, I don't really see
how the octet count could be negative?
So maybe the second format should be %u?
That's minor though.)
Best,
