\s+ will at least one space
That's "whitespace". "space" is a character which happens to be whitespace, there are four other characters that match it as well (tab, space, carriage return, line feed, vertical tab)

[Added - sauoq caught me out on the VTAB vs FF character. I never use either so I forget that part. I knew chr(12) was whitespace (through running perl -le '$,="\n"; print grep chr() =~ /\s/, 0 .. 255') but I didn't remember what it was.]

    Yes, of course; "whitespace."

    Your list is wrong though. You are missing form-feed ("\f") and you have incorrectly included a vertical tab.

    perl -le 'print "\f" =~ /\s/ ? "match" : "no match"'    # form-feed
perl -le 'print chr(11) =~ /\s/ ? "match" : "no match"' # 11 is vertic
+al tab.
