I recently needed to change the permissions of all files inside a directory (only files but not folders), including subdirectories. From the command line in Mac OS X, I ran this command with success which changed all files recursively to 666 (rw-rw-rw-):

sudo find . -type f -exec chmod 666 {} \;

Likewise, to change only directories to 777 (rwxrwxrwx), I used:

sudo find . -type d -exec chmod 775 {} \;

This adds the default location of the MySQL binary to your shell environment.

Then, you need to force the system to reload your .bash_profile file. Again, from terminal, enter:

. ~/.bash_profile

Now, to access MySQL from the command line, you only need enter:
