chmod 775 filename

Each group of three is rwx, where x=1, w=2, r=4. 4+2+1=7, so rwx is 7. rx=1+4=5.

Hi Corona,

Thanks.

chmod 775 filename -- Do this permission have all read,write and execute? if so what is the difference between chmod 777 filename and chmod 775 filename? Could you please clarify?

Regards,
Maddy

The difference is 2. And 2 means w.

Each digit is a sum of r, w, and x, where r=4, w=2, x=1. So --x=1, -w-=2, -wx=3, r--=4, r-x=5, rw-=6, rwx=7.

Code:
r w x   r w x   r - x 

4+2+1=7 4+2+1=7 4+0+1=5

Hi Corona,

I don't understand. Could you please tell me the difference between chmod 777 filename and chmod 775 filename?

Here again is the complete meaning of all those digits:

Code:
7 = rwx
6 = rw-
5 = r-x
4 = r--
3 = -wx
2 = -w-
1 = --x
0 = ---

Since 7 means rwx, and 5 means r-x, you can pile them together like 775 to get rwxrwxr-x.
