can anybody tell me what this is and how can i go to this directory. cause i'm trying to download a script into my server and the instructions on the scrip is this, "please make sure the log directory is writable (chmod 777). " so how can i do that?

This is a unix command. Can't tell you a lot because I don't work with unix myself, but I can tell you that the chmod 777 command makes a file on unix server available to read, write, etc.

Check out http://www.zzee.com/solutions/unix-permissions.shtml
which explains unix permissions,
and
http://www.zzee.com/solutions/chmod-help.shtml
which is the chmod help file.

Good Success!

i've done reading it and i notice that my FTP client doesnt have that permission to edit unix. do you know or can give me some idea what FTP client software that can do that? and also free to download. thanks

Im a linux junky, so I'll try to explain it...I'm sure the sites above give a good explaining.. but who wants to visit another site?

chmod stands for "Change Mode".

The numbers part is a little more complicated.... "777" is three numbers..to be nerdy and specific.. it is three 3 digit binary (base 2) numbers converted into three 1 digit octal (base 8) numbers.

The first number stands for "user", the second group stands for "group" and the final number stands for "other". There are three possible things that can be done with a file: read, write, and execute.. Here is a little reference:

execute = 001 in binary = 1 in octal
write = 010 in binary = 2 in octal
read = 100 in binary = 4 in octal

So where does the 7 come from?

7 in binary = 111 in decimal = read, write, execute

So you get:

read write execute = 111 = 1 + 2 + 4 = 7
read write no execute = 110 = 4 + 2 = 6
read no write execute = 101 = 4 + 1 = 5
read no write no execute = 100 = 4
no read write execute = 011 = 2 + 1 = 3
no read write no execute = 010 = 2
no read no write execute = 001 = 1
no read no write no execute = 000 = 0

Make sense?

To make a file "chmod 777" you would simply type:

chmod 777 filename.ext

in the terminal.

I'm pretty sure you should be able to use an SSH client, such as PuTTY to edit unix

To chmod a file on your host from windows:

• Open your site in the ftp program
  
• Right click on the file on your site you want to chmod
  
• Select properties
  
• Enter 777

chmod sets permissions for a file eg: read, write, execute for the owner (you) and guests (any one who views the file...this includes programs). 777 means anyone can do anything with the file.

Thanks a million for the explanation below. I know all of the other posts are great, but I was lost. I read this post and resolved my problem right away.

Thanks!!!!

Edit: I meant to tell you that I joined this board just to say thanks!

Total Commander can change the attributes of files on the server... exactly what you need. You should also be able to do that over Cpanel or whatever admin panel you use for your server. Just find the file manager and it should be easy to figure it out.

If you are modifying the CHMODS to install a script or to set up a script for server handling, make sure you don't change the CHMODs on the wrong files. Doing so can compromise your site to hackers.

You should be able to change CHMODS using most FTP clients, unless your hosting company has restrictions on this. I know my hosting company does but I am able to do it in SSH.
