Full Discussion: Execute a command with root user
Top Forums Shell Programming and Scripting Execute a command with root user Post 302987965 by rbatte1 on Monday 19th of December 2016 08:00:31 AM

Additionally, if you run this:-
Code:
sudo cat /tmp/tmp.file >>/etc/logger

... what you are trying to do is to run cat with privileges so it can open whatever file out want, HOWEVER the >> is in your current, non-privileged shell so if you cannot open the file, then you will get the bash: /etc/logger: Permission denied seen in post 1

You haven't answered vbe's question about what /etc/logger is. Is this just a plain log file, or are you trying to write to the system logs? If it is the latter, overwriting/appending to it would be a bad thing. Usually /etc contains configuration information that you would not want to routinely overwrite/append. Depending on your actual desires, this is more likely to be a file in /var somewhere.

What are you actually trying to achieve?
