This assumes [`ugrep`](https://github.com/Genivia/ugrep) is installed. `ugrep` may not be the absolutely fastest `grep` replacement out there, but it has a substantially faster regular expression engine (invented by Genivia) than most alternatives which usually rely upon Boost (which *is* fast already!).

It also assumes that `whois` is installed and listed in `$PATH`. Adapt as appropriate.

The final `sort | uniq` may be replaced with `sort --unique` (if that option is available) and should improve things a little.


```bash
LOGFILE=/var/path/something
ug -e '(\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})' -P --format="%1%~" $LOGFILE | uniq | while read -r line; do whois -H $line | ug -e '(AS\d{1,6})' -P --format="%1%~"; done | sort | uniq

Convert files from ISO-8859-1 (Latin-1) to UTF-8, recursively

This requires recode to be installed (brew install recode or apt install recode).

The example shows HTML files only. Adjust as required.

Process:

1. (Recursively) find all files that end with *.htm or *.html.
2. For each match, check its file type using file.
