 ### Splitting PDF files
-`$ convert -density 600 (input.pdf) -crop 50x100% +repage (out.pdf)`  
+
+```sh
+$ convert -density 600 {INPUT.PDF} -crop 50x100% +repage {OUT.PDF}
+```
 
 ```
 -density: adjusts the quality of the resulting pdf. Higher values look better, but take longer to process

 ## Find
+
 ### Change filtered permissions
+
 Using find with its `exec` switch one can set different permissions based on the usual find filters.  
 One example would be only changing file or directory permissions.
-`$ find (directory) -type f -exec chmod 744 {} +`  
+
+```sh
+$ find (directory) -type f -exec chmod 744 {} +
+```
+
 Replacing `-type f` with `-type d` would execute the `chmod` for directories instead.
 
 ## Various
+
 ### Overwrite disk with pseudorandom data
+
 Using openssl on CPUs with AES acceleration one can create pseudorandom data with high speeds.  
 Much faster than `/dev/urandom` at least
-`# openssl enc -aes-128-ctr -md sha512 -pbkdf2 -nosalt -pass file:/dev/urandom < /dev/zero | pv > (target disk)`  
+
+```sh
+# openssl enc -aes-128-ctr -md sha512 -pbkdf2 -nosalt -pass file:/dev/urandom < /dev/zero | pv > {TARGET DISK}
+```

 Around 2GiB/s on my Ryzen 7 1700x if output to `/dev/null`
 
 ### Formatted csv in terminal
+
 > [From Pretty CSV viewing on the Command Line](https://www.stefaanlippens.net/pretty-csv.html)
 
-`$ column -t -s, < (file.csv)`  
+```sh
+$ column -t -s, < {FILE.CSV}
+```
+
+### Download directory from webdav
+
+Using `wget`, it's possible to download directories recursively from WebDAV.
+
+```sh
+$ wget -r -nH -np --cut-dirs=1 --user={USERNAME} --password={PASSWORD} https://WEBDAVHOST/DIR/DIR
+```
