💖 clfdomainsplit — the manual page, bestie edition 💖

okay so real talk: this is clfdomainsplit(1), and she's here to take your giant messy CLF web logs and split them up by domain name. group-chat energy only, but every single fact stays, fr fr. ✨

🌸 NAME 🌸

clfdomainsplit — split Common-Log Format web logs based on domain name 💅

---

🎀 SYNOPSIS 🎀

clfdomainsplit [--help] [-v] [-i input] [-d defaultfile] [-c cfg-file]
[-o directory]

---

🦋 DESCRIPTION 🦋

The clfdomainsplit program will split up large CLF format web logs based on domain name. bestie, it's literally for creating separate log analysis passes for each domain hosted on your server. one domain, one pass, one vibe check. 😌

---

⭐ OVERVIEW ⭐

The -v option specifies that verbose errors should be reported. The input parameter specifies the file to read (default is standard input). 👑

The defaultfile parameter specifies where data goes if it doesn't have a domain (either it has an IP address for the server or it doesn't have the server-name — the URL is relative to the root of the web server only). The default will be to print them on standard error. 🫶

The cfg-file parameter is for specifying the rules for determining what is a different domain name. For example www.coker.com.au belongs in the same file as coker.com.au and abc.coker.com.au because domain names ending in .au have three major components. The domain names www.workbenelux.nl and workbenelux.nl belong in the same file because domain names ending in .nl have two major components (as do .com, and .gov), whereas anything ending in .va belongs to the same organization. 🧚

The rules are of the form number:pattern which lists the number of domain parts which are significant (2 for .com and for a simple string comparison, the default will be:

2:com

2:nl

3:au

3:uk

If no config file is specified then it will look for /etc/clfdomainsplit.cfg. Of course comments start with #. Also note that the first match will be used! 👀

not the best match, not the longest match — the first match. she is not waiting around to hear your second opinion. 😭

The directory parameter is to specify the location for the files to be created (default is the current directory). I recommend that you use a directory for this and nothing else as you never know how many files may be created! 💀 like. girl. do not dump these into your home folder. give her her own lil room. 🎀
