what is owner?
 

I have installed fedora red hat linux myself .But Idont have permission to create folder in "/". And I am installing an application that need to create folder there .The error massage is " you are not the owner "
I want to know what is the owner & how can I find it?

Type the following in a terminal
It will give you the root access, you need to enter the password after that, :D

man su

Here the owner means the "root" who is the superuser, you can see the details with the following command:

if you know your root account password then issue:

It will ask for root password, provide the same and you'll be logged in as root, now you can create the folder in that location.....

It doesn't works?
 

I have typed the code but still can't create a folder in "/" and the same error "you are not the owner"!

Post exactly what your terminal says i.e.

when you did su did it ask for password , if yes, then what happened ?

That means you are still not logged in as superuser.......try the command "su" once again.........

Hi,
if you "still can't create a folder in "/"", you really shouldn't do it, until you want install the system again. This is the base knowledge.

First to answer your question - owner is the person that either owns the directory or owns the file that you are trying to edit. With linux folders and files are actually the same.

As for the error you will need to do
the dash after su is important. Without it you get his rights but not full rights so su - will give you full access.

Also what application are you trying to install? you may want to install it into another directory. Possible directories would be /opt, /usr or /usr/local.
