File Type. This is used with fcontext. Requires a file type as shown in the mode field by ls, e.g. use d to match only directories or f to match only regular files. The following file type options can be passed: f (regular file), d (directory), c (character device), b (block device), s (socket), l (symbolic link), p (named pipe). If you do not specify a file type, the file type will default to "all files".
