printf [ -v name ] format [ arg ... ]
Print the arguments according to the format specification.
Formatting rules are the same as used in C. The same escape
sequences as for echo are recognised in the format. All C
conversion specifications ending in one of csdiouxXeEfgGn are
handled. In addition to this, `%b' can be used instead of `%s' to
cause escape sequences in the argument to be recognised and `%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; otherwise the argument is evaluated as an arithmetic
expression. See the section `Arithmetic Evaluation' in zshmisc(1)
for a description of arithmetic expressions. With `%n', the
corresponding argument is taken as an identifier which is created
as an integer parameter.
Normally, conversion specifications are applied to each argument
in order but they can explicitly specify the nth argument is to be
used by replacing `%' by `%n$' and `*' by `*n$'. It is
recommended that you do not mix references of this explicit style
with the normal style and the handling of such mixed styles may be
subject to future change.
If arguments remain unused after formatting, the format string is
reused until all arguments have been consumed. With the print
builtin, this can be suppressed by using the -r option. 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.
The -v option causes the output to be stored as the value of the
parameter name, instead of printed. If name is an array and the
format string is reused when consuming arguments then one array
element will be used for each use of the format string.
