print FILEHANDLE sprintf(FORMAT, LIST) , except that
$\ (the output record separator) is not appended. The FORMAT and the LIST are actually parsed as a single list. The first argument of the list will be interpreted as the
printf format. This means that
printf(@_) will use
$_ as the format. See sprintf for an explanation of the format argument. If
use locale (including
use locale ':not_characters' ) is in effect and POSIX::setlocale() has been called, the character used for the decimal separator in formatted floating-point numbers is affected by the LC_NUMERIC locale setting. See perllocale and POSIX.
For historical reasons, if you omit the list,
$_ is used as the format; to use FILEHANDLE without a list, you must use a real filehandle like
FH , not an indirect one like
$fh . However, this will rarely do what you want; if $_ contains formatting codes, they will be replaced with the empty string and a warning will be emitted if warnings are enabled. Just use
