findex(printf)
item(tt(printf) var(format) [ var(arg) ... ])(
Print the arguments according to the format specification. Formatting
rules are the same as used in C. The same escape sequences as for tt(echo)
are recognised in the format. All C format specifications ending in one of
csdiouxXeEfgG are handled. In addition to this, `tt(%b)' can be used
instead of `tt(%s)' to cause escape sequences in the argument to be
recognised and `tt(%q)' can be used to quote the argument in such a way
that allows it to be reused as shell input. With the numeric format
specifiers, if the corresponding argument starts with a quote character,
the numeric value of the following character is used as the number to
print.
If arguments remain unused after formatting, the format string is reused
until all arguments have been consumed. If more arguments are required by
the format than have been specified, the behaviour is as if zero or an
empty string had been specified as the argument.
