i know i must use chmod but which one and what the struck of the code line to area and not file? "chmod mode file(s)"

which one? chmod is a core utility - you shouldn't have more than one on your system.

what the struck? - don't even know what you're asking there.

I'd be very leery of changin permissions (modes) of /var and /www - the former is used by key system files that might not work if you changed their permissions due to security safeguards and the former is used for your web server usually.

Typing "man chmod" or "info chmod" should give you a lot of info about use of the chmod command.

Breifly:

You can set permissions in the form read/write/execute by numeric values with 4 = read, 2 = write and 1 = execute. The permissions are set for each of owner, group and world (world being everyone else).

To set permissions for everyon to read, write and execute you do
4+2+1, 4+2+1, 4+2+1 = mode 777:

chmod 777 file(s).

If you only wanted to give read, write and execute to the owner but read to group and world you do: 4+2+1, 4, 4 = mode 744:

chmod 744 file(s)

If you wanted to give read and execute to owner and group but not world you do: 4+1, 4+1, 0 = mode 550:

chmod 550 file(s).

You can see current permissions of a file by doing:
ls -l file(s).

The left most columnt contains the permissions as r(ead), w(rite) and e(x)ecute prepended by a special character.

So a file that has 777 would show:
-rwxrwxrwx

A file that has 744 would show:
-rwxr--r--

A file that as 550 would show:
-r-xr-x---

The first position has special meanings with the most common being:
- = Regular file
d = Directory
l = Symbolic link
c = Character device file
b = Block device file

But if you really don't know the above already I'd strongly urge you not to change mode (by the way chmod is a contraction of change mode) of anything in /var at least. You should restrict your experimentation to your home directory as you're apt to break something until you've done more reading.

This is what I would advise instead of chmod...

Create a directory in your /home directory where your webpages and such get stored. Then navigate to that directory in Nautilus. Let's say, for example, that the folder is /home/akakak/web

Then, press Alt-F2 and type Enter your sudo password and navigate to /var/www

So now you have two windows open--one with root privileges, one with user privileges. Middle-click-drag /home/akakak/web to /var/www and then select link here.

Now whatever you put in /home/akakak/web will be in /var/www.
