 | `-e LOG_TYPE_FILE_PATTERN=`         |   (Optional) Only to be used with LOG_TYPE=NCSA_COMBINED or TRAEFIK. This parameter will pass along the file type you are trying match. For example you can pass -e LOG_TYPE_FILE_PATTERN="*.log" or -e LOG_TYPE_FILE_PATTERN="access.log". The default is *.log. Please keep it simple as I have not tested this completely.

+| `-e ENABLE_BROWSERS_LIST=True/False`         |   (Optional) Defaults to False. Set to true if you would like to enable the [goaccess browsers.list](https://github.com/allinurl/goaccess/blob/master/config/browsers.list) file.     |
+| `-e CUSTOM_BROWSERS=`         |   - (Optional) Consumes the list of provided custom browsers. This is a comma separated list containing the custom browser(s) in the format `Browser:Browser_category`.<br/>- If your custom browser is already defined in the default `browsers.list` file, it will not be added. However, the `Browser_category` can be reused.<br/><br/> CUSTOM_BROWSERS list example: `Kuma:Crawlers,TestBrowser:Crawlers,Kuma:Uptime,Discordbot:Crawlers`<br/><br/>For the example above, only `Kuma:Crawlers` and `TestBrowser:Crawlers` will be appended to the `browsers.list` file. <br/><br/>`Kuma:Uptime` is ignored as the browser `Kuma` has already been defined in `Kuma:Crawlers`. `Discordbot:Crawlers` is ignored as the browser `Discordbot` is already defined in the [default browsers.list file](https://github.com/allinurl/goaccess/blob/master/config/browsers.list)<br/><br/>Note for users using CUSTOM LOG_TYPE:<br/><br/>If your `goaccess.conf` file references a browsers.list file other than the one located in the `/goaccess-config/ directory`, the CUSTOM_BROWSERS variable will be ignored.    |
