\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.]
