I don't know if it will do what you want, but check out the "join"
program. From 'man join': "For each pair of input lines with identical
join fields, write a line to standard output."
It matches on fields, it doesn't search the entire line. But, if the
data you are searching for in your log files can be described as a
'field', it might work.
