Exercise #8: Counting and Sums with awk

“You can use an awk script to increment or count the total
number of occurrences of a specific aspect. The awk operators post
helps explain some of the options you may consider. The example
below starts with a BEGIN section that can use several different
types of field separators. Then in the main body it searches for
the text string “httpd” which is the Apache web server and counts
those. Each time awk loops through the records it increments the
count. Then in the END section the final Apache count can be
provided.

awk file: count

BEGIN {FS=”[ : ]”}
/httpd/{count++}
END {print “Apache Servers Now Running: “count; print “Total Number
of Records: ” NR}
