string search
Hi,
There is a very big flat file called Protokoll.txt
keep on appending more and more records
wc -l also will take lot of time, it is production data.
from this file I want to list out the line containing
last occurence of the string "ServedParty=123".
if I give like this :
$grep "ServedParty=123" Protokoll.txt
What I want is Last line of the above result.
It will take lot of time, because it will search from
top, but I need to search from bottom.
Kindly mail me to :
::email removed::
