Awk scans input files for specified patterns and can perform an associated action when a line of the file matches the pattern. This is the version of awk described in "The AWK Programming Language", by Al Aho, Brian Kernighan, and Peter Weinberger (Addison-Wesley, 1988, ISBN 0-201-07981-X). http://cm.bell-labs.com/cm/cs/awkbook/index.html -- Josh Gilliam
