On Unix/Linux systems, file types are not defined by the file extension (as Microsoft Windows does). Unix/Linux systems use the file command, which examines the file's contents to determine a file's type. This recipe collects file type statistics for a number of files. It stores the count of files of the same type in an associative array.
The associative arrays are supported in bash version 4 and newer.
