What is CHMOD 777 in Linux

Question

What is Chmod 777 ?. I just moved my site from Windows Hosting to Linux, Confused in file permissions, I read on many websites and tutorials to change file permission to chmod 777 but didn't got them what exactly this permission does. Can anyone help me understand this file permission thing?

Answer 2

0 – No permissions

1 – Execute

2 – Write

4 – Read

1+2 = 3 (exec + write)

2+4=6 (write + read)

and so on...

chmod 751 means...

7 is for user for which the file belongs (7 = 4 +2+1)

5 is for user group ( 5 = 4 + 1) so they can read and execute but not write

for rest of world it is 1 which means they can read it

Simple is that :)
