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!
(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.
