    Product Standard Commands and Utilities V4 (UNIX 03)
    Certification Program The Open Brand certification program
    Test Suite VSC version 5.2.5
    Test Identification POSIX.cmd/sort 5, 13
    Specification Shell and Utilities Issue 6
    Location in Spec See problem text.
    Problem Summary The tests fail on systems where sort -c does not write to stderr when
    the input is disordered.
    Problem Text Problem described in TIN.X.0061 for SUSv2 still exists in SUSv3, an
    equivalent TIN should be granted.

    According to the Commands and Utilities, Issue 5:

    "-c Check that the single input file is ordered as specified by the
    arguments and the collating sequence of the current locale. No output
    is produced; only the exit code is affected."

    The test code:

    CT_STDOUT=out.stdout
    CT_STDERR=out.stderr
    cmd=`OpenTP sort 5 A "Verify sort -c exits with 1 and writes
    stderr if not sorted."`

    $cmd -c unsorted1.txt > $CT_STDOUT 2> $CT_STDERR
    CT_EXIT_VALUE=$?
    if [ $CT_EXIT_VALUE -ne 1 ]; then
    SetResult $TET_FAIL "Expected exit code = 1; Received
    $CT_EXIT_VALUE"
    else
    SetResult $TET_PASS
    fi

    if [ -s $CT_STDERR ]; then
    SetResult $TET_PASS
    else
    SetResult $TET_FAIL "Standard error is empty"
    fi

    The failure occurs because $CT_STDERR is not of size > 0. However,
    according to the standard, it should not be size > 0 because no output
    would have been produced.

    Since Base Working Group resolution bwg98-002 has been changed, it is
    not reasonable for the test to expect output to stderr with the -c
    option.

    Review Recommendation Temporary Interpretation (TIN)
    Review Response From the problem text it appears that the submitter intended to request
    a TIN, not a TSD, and probably selected TSD on the web form by mistake.

    No change to the relevant text was made between SUSv2 and SUSv3, so this
    SUSv2 grey area still exists in SUSv3 and an equivalent UNIX03 TIN
    should be granted.

    Review Resolution Temporary Interpretation (TIN)
    Review Conclusion The TSMA believes that the test is correct relevant to its intention,
    however the TSMA notes that their is known gray area in the
    specification, and therefore this PR represents a Temporary
    interpretation pending resolution of the ambiguity
