Meaning of "> /dev/null 2>&1"

Hi,

I am new into UNIX shell scripting and I am wondering what is the meaning of the below text which appears at the end of each line in the ".sh" file:

> /dev/null 2>&1

For example, the line below:

sh $HOME/stats/Rep777/Act_777.sh omc omc > /dev/null 2>&1

I know for sure what "sh $HOME/stats/Rep777/Act_777.sh omc omc" does mean but I don't have any idea about the rest which is " > /dev/null 2>&1".

Thanks in advance.
