I understand in Linux that to redirect the output from a screen to one of my files, I can use either the > or tee. But I can't figure out why the output is actually still the output to the screen (and now written to the file). Would there be a way to redirect the output just to the file?

Obtaining an elapsed-time sorted list of Unix processes from a shell

I would like to obtain a sorted list of processes, sorted by elapsed time. I am aware of ps -o etime etc, but how exactly do i sort by a field with format [[dd]:[hh]]mm:ss ? Or is there a different way altogether to ask the OS to return a sorted list of processes, sorted by elapsed time? Thanks.
