Very often I need to review some logs of a given service.
I've found that #emacs is the perfect tool for analyse them. This is what I'm using:
- Occur (M-s o). Ask for a regexp and opens a new buffer with the matching lines. You can click on those lines
- `highlight-lines-matching-regexp`. This will mark in the buffer the lines. This helps a lot visualizing the important events.
- `flush-lines`: Delete all the lines that matches a regexp. To remove lines that are not adding any value
@robjperez I have an eerily similar workflow
I also use `keep-lines` which is the opposite of `flush-lines`
I used to use `grep -C n` to get n lines of context before and after each regex match, but I just now realise M-x occur takes a prefix argument equivalent to `grep -C n`!
