Missing argument in printf at -e line 1.
Missing argument in printf at -e line 1.


$ perl -le " use strict; use warnings; printf qq{%-12s %-12s\n}, @ARGV
+ " what
Missing argument in printf at -e line 1.

$ perl -le " use strict; use warnings; printf qq{%-12s %-12s\n}, @ARGV
+ " what what

$ perl -le " use strict; use warnings; use diagnostics; printf qq{%-12
+s %-12s\n}, @ARGV "
Missing argument in printf at -e line 1 (#1)
    (W uninitialized) A printf-type format required more arguments tha

$ perl -le " use strict; use warnings; no warnings q{uninitialized}; p
+rintf qq{%-12s %-12s\n}, @ARGV "


$ perl -le " use strict; use warnings; no warnings q{uninitialized}; p
