That's an odd ps function, but wouldn't duplicate output the way you've
described. The aliases look fine.
What happens if you redirect to a file?
ps -ef | grep yum > output; cat output
You could also try 'command ps -ef' to see if bypassing the function does
anything (I notice it's invoking /bin/ps, but that should be the same utility
as /usr/bin/ps).
