It is often when I get on a box I need to install something like Nmap for something simple. If I know the system is setup for a respository, I do not need to watch the messages from the install, I will know soon enough if Nmap is installed when I try to use it.
I would like to do a yum -y install nmap & allmessages > /dev/null.
The syntax is not correct however you likely understand what I want. I just want it to install and not send out any messages during the install to mess up the typing I am doing.
