The 40k-rep-heavy user Gilles commented on this question Why do you need the "./" when executing programs in the current directory? (ups - why is no link-button here?) that it is a possible duplicate.
Looks like a plain-old-real-exact duplicate to me. I flagged it, but there is no explicit flag-option, like on other SE-sites. Intentionally? Do we encourage duplicates?
'exact duplicate' should be a radio-button-option in the flag-dialog!
And then the question should be closed, shouldn't it? It should!
Update:
(Rewriting the whole question, because, from the answers, I see, that the problem is somewhere else.)
The flag option 'exact duplicate' is hidden behind the entry does not belong here
.
If the original belongs here, the problem isn't, that it does not belong here, but that it is already here.
I didn't find the option, while I wanted to flag above mentioned post, because, well, it belongs here - it is just a duplicate.
