"Permission denied" Problem

[Ravi Shanmugam]

Hi All,
 
I have a query on accessing a root file as a non-root user. The problem
is described as follows.
 
I wanted to execute the following command 
 
cat /root/.ssh/id_rsa.pub > /abiscard/local/root/.ssh/authorized_id 
 
as a non-root user i.e "backup" user. Is there any way I could do this.
This is for my project requirement.
 
Your reply will be well appriciated.
 
Regds,
Ravi R.S
