Cleaned up the image files. Cover images go under /static and in-post images are now in /content/posts/img. Edited and rebuilt some existing posts for this structure. I also removed my birdnet post and put it back in drafts so I can publish it as some future date.

+This post will act a bit like a living document of all the useful commands and short scripts that I use regularly. Some will
+be as simple as `ls | wc -l` which counts the number of files in your current working directory, and others will be better
+suited to small scripts. As this grows, I will hopefully break these into more logical categories.
+
+## Find by File type
+
+This command will find every file in your current working directory by the specified file extension.
+
+```bash
+find . -type f -name '*.txt'
+```
+
+As a bonus, if you wanted find everything _except_ that file extension, you can add a `!` before name. In other words:
+
+```bash
+find . type -f ! -name '*.txt'
+```
+
+I usually use commands like this to clean up files that I don't need, be it file extensions I don't need anymore, or anything
+with a specific word in its file name, so adding `-delete` at the end of the command lets me delete those files.
+
+```bash
+find . type -f -name '*.txt' -delete
+```
+
+## List Files & Dir +
+
+Using `ls` is a _key_ command for anyone that works within a command line. If you've used `ls` before, then you've also
+likely used or created an alias for `ls -la` which will display the files, their user:group ownership, permissions
+(`drwxrwxrwx`) and dates created + modified.
+
+What if you just want to found the number of files? Not measuring disk usage or free space, but the equivalent of `len` for
+an array, the array being your current working directory. Enter `wc`!
+
+```bash
+ls | wc- l
+```
