## read\_logs.rb
`bin/read\_logs.rb` looks in the `log/` directory for files ending with `.log`,
`.log.1`, `.log.2.gz`, `.log.3.gz` and so forth. It filters out lines starting
with a timestamp, `yyyy-mm-ddThh:mm:ss`, followed by random characters and a
custom string provided as the only command line parameter. Finally
it outputs all matched content after the provided string along with the date.
The log files are read in the order based on the number in the filename.
For example calling the script as
```sh
./bin/read_logs.rb 'doctrine.INFO:'
```
on a log file containing
`[2025-02-04T19:51:49.356093+01:00] doctrine.INFO: Disconnecting [] []`
will print:
```
2025-02-04 (Disconnecting [])
```
