https://bugzilla.redhat.com/show_bug.cgi?id=817244 mentions that unlike most other tools, where --help or --version prevent all further parsing of all later options, virsh was strange in that --version stopped parsing but --help tried to plow on to the end. There was no rationale for this original implementation (since 2005!), so I think we can safely conform to common usage patterns. * tools/virsh.c (main): Drop useless 'help' variable. --- I think the intent might have been to someday allow: virsh -h foo to be short for virsh help foo but since that hasn't been implemented in 7 years, I think it is smarter to be consistent with other tools instead. tools/virsh.c | 15 ++------------- 1 files changed, 2 insertions(+), 13 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index e177684..7159744 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -20179,7 +20179,6 @@ vshAllowedEscapeChar(char c) static bool vshParseArgv(vshControl *ctl, int argc, char **argv) { - bool help = false; int arg, len; struct option opt[] = { {"debug", required_argument, NULL, 'd'}, @@ -20206,7 +20205,8 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) } break; case 'h': - help = true; + vshUsage(); + exit(EXIT_SUCCESS); break; case 'q': ctl->quiet = true; @@ -20251,17 +20251,6 @@ vshParseArgv(vshControl *ctl, int argc, char **argv) } } - if (help) { - if (optind < argc) { - vshError(ctl, _("extra argument '%s'.
