FLicKeR (File Line Keeper and Remover) will read a text file and keep or remove certain lines that contain the text you specify. One of its most useful applications is that it makes the process of evaluating log files (such as keyboard recorders and web page statistics) much faster and easier. In the case of keyboard recorders, often much of the information is not needed, so removing all the lines with the unneeded information allows you to more efficiently look at the lines that need to be looked at. In the case of web page statistics, keeping only particular lines allows you to compare information in a much more useful way. It will save you countless hours and make evaluating log files much faster and considerably easier.
