Use chmod like a Pro..
Look at the Image.

Whatever you want to set, simply add up the numbers
and use chmod <number> <file>

Example:
chmod 755 = -rwxr-xr-x
chmod 644 = -rw-r--r--
chmod 777 = -rwxrwxrwx

and so on.

Thanks for that, the image is gold.
I not mentioned octal mode, and man chmod is quite bare-bone itself (it hardly explains how octal mode works), but usually I prefer using octal mode numbers.
