awk
ampersand (&) in repl with the substring of string which matches regexp. An
ampersand preceded with a backslash ('\') is interpreted as the literal
ampersand character. An occurrence of two consecutive backslashes is
interpreted as just a single literal backslash character. Any other occurrence
of a backslash (for example, preceding any other character) is treated as a
literal backslash character. If repl is a string literal, the handling of the
ampersand character occurs after any lexical processing, including any
lexical backslash escape sequence. If you omit string, sub uses the current
record instead. sub returns the number of substrings replaced (which is 1 if
it found a match, and 0 otherwise).
n = gsub(regexp, repl, string)
Works the same way as sub, except that gsub replaces all matching
substrings (global substitution). The return value is the number of
substitutions performed.
str = sprintf(fmt, expr, expr...)
Formats the expression list expr, expr, ... using specifications from the string
fmt, and then returns the formatted string. The fmt string consists of
conversion specifications that convert and add the next expr to the string,
and ordinary characters that sprintf simply adds to the string. These
conversion specifications are similar to those used by the ANSI (see
SC09-4812 IBM Open Class Library Reference, Vol.1).
Conversion specifications have the form
%[-][0][x][.y]c
where
- Left-justifies the field; default is right justification.
0 (Leading zero) prints numbers with leading zero.
x Is the minimum field width.
y Is the precision.
c Is the conversion character.
In a string, the precision is the maximum number of characters to be printed from
the string; in a number, the precision is the number of digits to be printed to the
right of the decimal point in a floating-point value. If x or y is * (asterisk), the
minimum field width or precision is the value of the next expr in the call to sprintf.
The conversion character c is one of following:
d Decimal integer
i Decimal integer
o Unsigned octal integer
x,X Unsigned hexadecimal integer
u Unsigned decimal integer
f,F Floating point
e,E Floating point (scientific notation)
g,G The shorter of e and f (suppresses nonsignificant zeros)
c Single character of an integer value; first character of string
s String
The lowercase x specifies alphabetic hex digits in lowercase, whereas the
uppercase X specifies alphabetic hex digits in uppercase. The other
uppercase-lowercase pairs work similarly.
