Description of the bug:

Environment:

fio --enghp

fio: unrecognized option '--enghp' fio: unrecognized option '--enghp' Did you mean enghelp?

I don't understand this issue. You're using an unknown option, and fio helpfully tries to tell you that you probably meant --enghelp.

Sorry for the unclear report, I type --enghp by mistake, but the fio outputs two same lines of fio: unrecognized option '--enghp' , I think just one line is enough.

# fio --enghp
fio: unrecognized option '--enghp'       
fio: unrecognized option '--enghp'
