RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
In mcelog man page is briefly mentioned --help argument:
"
When the --cpu=cputype option is specified set the to be decoded CPU to cputype. See mcelog --help for a
list of valid CPUs. Note that specifying an incorrect CPU can lead to incorrect decoding output. Default
is either the CPU of the machine that reported the machine check (needs a newer kernel version) or the CPU
"
when you run mcelog --help it would at first write: "mcelog: unrecognized option '--help'" and after that it prints out help message with list of command to stderr and mcelog would return error code 1.
Because --help argument is mentioned in manpage I think it should not print "unrecognized option" or it should not be mentioned in manpage.
My recomendation.
add --help to argument list, print help message to stdout, and return 0
OR
remove --help from manpage
