Excellent, this is what I was looking for.

@Braiam Yes, those `, two at different places in the same inline code.

I tried pretending to edit your post, but that edit link is dimmed. Anyway, asking that question again, can not I have two back quotes in the same inline code?

Please show you source to let us know how you have done it. How can I put, "echo [single back quote] cat file.txt[single back quote]", where the whole thing within double quotes need to be shown as code inline? Please see my original question. Also, please see the link on comment which provided one answer. Is there any other way? No escape character?

Found the answer here
