AWK - Assignment Operators
AWK supports the following assignment operators −
Simple Assignment
It is represented by =. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { name = "Jerry"; print "My name is", name }'
On executing this code, you get the following result −
Output
My name is Jerry
Shorthand Addition
It is represented by +=. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { cnt = 10; cnt += 10; print "Counter =", cnt }'
On executing this code, you get the following result −
Output
Counter = 20
In the above example, the first statement assigns value 10 to the variable cnt. In the next statement, the shorthand operator increments its value by 10.
Shorthand Subtraction
It is represented by -=. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { cnt = 100; cnt -= 10; print "Counter =", cnt }'
On executing this code, you get the following result −
Output
Counter = 90
In the above example, the first statement assigns value 100 to the variable cnt. In the next statement, the shorthand operator decrements its value by 10.
Shorthand Multiplication
It is represented by *=. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { cnt = 10; cnt *= 10; print "Counter =", cnt }'
On executing this code, you get the following result −
Output
Counter = 100
In the above example, the first statement assigns value 10 to the variable cnt. In the next statement, the shorthand operator multiplies its value by 10.
Shorthand Division
It is represented by /=. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { cnt = 100; cnt /= 5; print "Counter =", cnt }'
On executing this code, you get the following result −
Output
Counter = 20
In the above example, the first statement assigns value 100 to the variable cnt. In the next statement, the shorthand operator divides it by 5.
Shorthand Modulo
It is represented by %=. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { cnt = 100; cnt %= 8; print "Counter =", cnt }'
On executing this code, you get the following result −
Output
Counter = 4
Shorthand Exponential
It is represented by ^=. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { cnt = 2; cnt ^= 4; print "Counter =", cnt }'
On executing this code, you get the following result −
Output
Counter = 16
The above example raises the value of cnt by 4.
Shorthand Exponential
It is represented by **=. The following example demonstrates this −
Example
[jerry]$ awk 'BEGIN { cnt = 2; cnt **= 4; print "Counter =", cnt }'
On executing this code, you get the following result −
Output
Counter = 16
This example also raises the value of cnt by 4.
