>Description:
using the following command (inline or in script)

    printf "-h, --help       show help"

the printf command raise the error

    printf: illegal option -- h
    usage: printf format [arguments ...]

it should be ok if printf accept options, but this is not the case (as in the previous message):

    usage: printf format [arguments ...]

workarounds:

    printf "\-h, --help       show help"
    printf "%s" "-h, --help       show help"
