# `summertail` Summarize your `tail -f` output, with regexes
> You won't be able to count how many apache 200's are in the logs, so use a regex counter.
> Watching hundreds of lines of log files scroll by doesn't mean you know what happened
## Usage
`summertail DELAY REGEX1 REGEX2 ...`
Reads input from stdin, and for each line keeps track of how many of each REGEX is matched. Every `DELAY` seconds, the counters are reset, and a `\n` is printed.
The last column (`other`) is incremented for every line which doesn't match any of the regexes. If a line matches more than one regex, it will be counted for each regex.
If the `REGEX` starts with `!` it will invert the regex. i.e. it counts lines which _don't_ match that regex.
## Installation
Install with `cargo install summertail`.
## Example
```bash
$ tail -f /var/log/apache2/access.log | summertail 10s ' 200 ' ' 3\d\d ' \!' 200 '
