Gathering IP's from a complicated log
- by Harry
I have a question regarding the use of some more advanced grep, awk, sed. I have a log file, for a proprietary MTA, that contains IP's in a string, delimited by [redacted]^~x.x.x.x^[redacted]. So far all of my grepping, awking, and sedding hasn't gotten me very far.
This log file has 331520 lines in it. My goal was to simply grep out the ip's, then do a for loop with sed, to sed 's/$i/redacted'. I'm including a sample of one of the log entries. If you all have any idea, I would be greatly appreciative.
