Mass-change of Directory/File permissions @ command line.

A Quick note on how to change permissions of a whole directory structure and/or all containing files.

1. Changing permissions of Files in a directory structure, (starting point is current directory)(Example: set all files to 644)
   
   Sudo find . -type f -exec chmod 644 {} \;
   
2. Changing permissions recursively of all directories from current directory as starting point. (Example: set directories to 755)
   Sudo find . -type d -exec chmod 755 {} \;
