Bash Current Directory Path

Gives you the full directory name of the script no matter where it is being called from. https://stackoverflow.com/questions/59895/getting-the-source-directory-of-a-bash-script-from-within Github Gist
SOURCE="${BASH_SOURCE[0]}"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
  DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
  SOURCE="$(readlink "$SOURCE")"
  [[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
 

Add browser and device name to WordPress body class

Github Gist

Recursively List Video Files URL’s

This will recursively list video files (currently filtered by a ‘.mp4’ preg_match) links when put at the root of a url. Rough and not pretty but it’s functional. Github Gist <?php function readDirs($path){ $dirHandle = opendir($path); while($item = readdir($dirHandle)) { $newPath = $path."/".$item; if(is_dir($newPath) && $item != '.' && $item != '..') { readDirs($newPath); } … Continued
