Navigating Linux files and folders

[colinga]

I have been trying to learn how to change a file's permissions and so i wanted to try and change the permissions for "cdrom0". So i opened a terminal and tried to navigate to cdrom0 by using: /home/colinga/media/cdrom0 but all i get back is:
No such file or directory? Could someone tell me what i am doing wrong please.

I went to the Home folder and from there i found the Media folder which contained cdromO. So i opened the Media folder and right clicked on cdronO and selected open in terminal. I then typed the following: sudo chmod g+w cdromO. Typed in my password. But i still keep getting: No such file or directory. Help someone please!

Hi colinga,
I'm unable to understand your problem correctly.
In General to change permission of any file try the following steps:
I want to change permission of file say /home/oss/example.txt


Step 1: First check whether the file exists or not. (provide absoulte path name.)

$ls -l /home/oss/example.txt
-rw-rw-r--  1 oss oss 2 May  6 15:07 /home/oss/example.txt

Yes we have that file.

Step 2:use chmod with absoulte path name.

$chmod g+x /home/oss/example.txt
$ ls -l /home/oss/example.txt
-rw-rwxr--  1 oss oss 2 May  6 15:07 /home/oss/example.txt

Have tried everything that i know of as well as help off Lakshmipathi but i still can't add the HTML file to a CD-RW. Think i'll go back to using Windows. At least i could get things done.

Hi - You probably don't need to change permissions to do that. It's possible that the file you're working with is a symbolic link (much like a Windows shortcut).

Have you tried using K3b to burn the file? You might be using the wrong set of steps to achieve something quite simple, but I know it takes time to adjust from using Windows to doing things the *nix way.

Hi Fingal i think you maybe right. Shall have a go burning the file to a CD-RW using k3b.
