grep string
You might want to copy all or part of the file to a temporary file name. This won't speed it up but it will help prevent from corrupting the log file that is being appended.
cp protokoll.txt /tmp/protokoll.txt
grep string /tmp/protokoll.txt
If you want to break down the file into smaller sections to search use the split command. Do an man on split to see how it works.
Then cp that output to the /tmp directory and grep away!
