Operators' Precedence

It determines how operators are grouped when different operators appear in a single expression. For example, * has higher precedence than +. So, if we have a + b * c ;it means multiply b and c and then add a to the result. Precedence of operators can be overridden by using parentheses.

This is table of AWK's operator precedence order from highest to lowest:

Operator	Description
(…)	Grouping
$	Field reference
++ or - -	Increment, decrement
^ or **	Exponentiation
+,  -,  !	Unary plus, minus, logical not
*, /,  %	Multiplication, division or remainder
+, -	Addition, subtraction
Space	String concatenation
< <= == != > >= >>	Relational operators
~ !~	Match and no match operator
in	Array membership
&&	Logical and
||	Logical or
?:	Ternary operator
= += -= *= /= %= ^= **=	Assignment operators group right to left

 

Let us take a look at the following table to summarize the meaning of expression operators:
