Does less support such > features now? Since version 424, Less has this: * New "&" command allows filtering of lines based on a pattern. But you need that version installed (it was released less than a year ago) to take advantage of this, and it doesn't seem to support the equivalent of delete-matching-lines; instead, you will need to invert the regexp manually. In my daytime job, I also need to browse huge log files. I love Less and use it for simple browsing and searching (the fact that it doesn't have Emacs limitations of size is sometimes very important). But as soon as I need to do something complex, like compare two large log files or jump between several places, I always fire up Emacs (if it's not up already), because it's just too painful with Less, even though features to do that do exist. If the file is too large, I just cut the interesting part with Sed.
