List Extensions Within Folder

It didn’t occur to me that Apache serves everything under a folder and the .git folder may well be under a folder (you can have your project up a level so there’s a single folder at the root of the project & that folder is DocumentRoot for the web site). Without knowing specific file names, you cannot get anything since directory browsing is disabled. But git has a well-known structure so browsing to /.git/index or really scary for someone who stuffs their password in the repo URL /.git/config is there and Apache happily serves it unless you’ve provided instructions otherwise.

A coworker brought up the intriguing idea of, instead of blocking the .git folder so things subordinate to .git are never served, having a specific list of known good extensions the web server was willing to serve. Which … ironically was one of the things I really didn’t like about IIS. Kind of like the extra frustration of driving behind someone who is going the speed limit. Frustrating because I want to go faster, extra frustrating because they aren’t actually wrong.

But configuring a list of good-to-serve extensions means you’ve got to get a handle on what extensions are on your server in the first place. This command provides a list of extensions and a count per extension (so you can easily identify one-offs that may not be needed):

find /path/to/search/ -type f | perl -ne 'print $1 if m/\.([^.\/]+)$/' | sort | uniq -c
