Description Ed Avis 2005-01-01 10:29:37 UTC

User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.7.5)

Description of problem:
hdparm --help writes help text to stderr and then exits with a failure
status.  But the GNU standard is for the help text to go to stdout,
and for the command to then exit with status zero.  For example:

% grep --help >/dev/null && echo yes
% hdparm --help >/dev/null && echo yes


Version-Release number of selected component (if applicable):
hdparm-5.7-2

How reproducible:
Always

Steps to Reproduce:
hdparm --help

Actual Results:  Usage text printed on stdout file descriptor and
hdparm exits with nonzero status.

Expected Results:  Usage text goes to stdout and exit status is zero.

hdparm prints the help text to stderr and exits with  failure status
if you omit a required parameter or use unsupported options such as
--help. It prints to stdout and exits with status zero if you run it
with the option -h to get help.
I've added support for --help and have built a new package.
