The in construct may also be used in a for loop to iterate over all the elements of an array. An element may be deleted from an array using the delete statement. The delete statement may also be used to delete
if (val in array) print array[val] If the array has multiple subscripts, use (i, j) in array. The in construct may also be used in a for loop to iterate over all the elements of an array. An element may be deleted from an array using the delete statement. The delete statement ma...

The while statement iterates over the data fields in the record and adds each value to the total variable and increments the counter variable i by 1. When the counter value becomes 4, the while condition becomes FALSE, and the loop terminates, going to the next statement in the script. Th...
The in construct may also be used in a for loop to iterate over all the elements of an array. However, the (i, j) in array construct only works in tests, not in for loops. An element may be deleted from an array using the delete statement. The delete statement may also be used...
The loop iterates over the arraya, printing each element followed by a space. Conditional Splitting Suppose you have a dataset like this: A1,100 B2,200 C3,150 D4,300 Suppose you want to split the first column if the second column’s value is greater than 150, otherwise, print the whol...
You can use the while loop to iterate over data with a condition. cat myfile 124 127 130 112 142 135 175 158 245 118 231 147 $ awk '{ sum = 0 i = 1 while (i < 5) { sum += $i i++ } average = sum / 3 print "Average:",average ...
The special operator in may be used to test if an array has an index consisting of a particular value: if (val in array) print array[val] If the array has multiple subscripts, use (i, j) in array. The in construct may also be used in a for loop to iterate over all the elements...
