user rights
 

i am using Ubuntu 8.04

i have a problem creating a new folder in Computer/Filesystem/etc/opt
i right click, and the "Create Folder" is grey in colour (unclickable)

is there a command i have to type in terminal so that i can create a new folder?
or is there any other methods?

thank you

Hi,
It seems you do not have permissions to create folder. If you are trying that as normal user, it is a security feature of linux wherein normal users do not have write permissions to system folders like /etc. Only root has that power.

In case you are root, but still cannot create folder, check the permissions on the parent folder. It should be writable. "man chmod" should help.
