Is it possible to do a multiline pattern match using sed, awk or grep.
When input matching a specified pattern is read, the action associated with that pattern is carried out. the awk shipped with qnx is a port of gawk (gnu awk).
This can change from one record to the next.
Thus, depending on the types of data in $1 and $2, awk does either a numeric or a string comparison.
If several patterns match, then several actions are run in the order in which they appear in the awk program.
