Hi I thought I'd ask this here as you guys helped me setup mrtg :) I've got the following pattern in a text file in linux. Target[description1].1.3.4.6.5.3.:string@xxxxxxxxxx Directory[description1]: server1 Target[description2].1.3.4.6.4.9.:string@xxxxxxxxxx Directory[description2]: server2 What I would like to do is replace the ip of each with the following value of "Directory". So for example I would like Target[description1].1.3.4.6.5.3.:string@xxxxxxxxxx to become Target[description1].1.3.4.6.5.3.:string@xxxxxxxxxxxxxxxxxxx How can I accomplish this using either C,perl,sed or awk Thanks Dan
