If I want to run a command using nohup and redirect the output to a file other than the default nohup.out I can use the following syntax to redirect stdout and stderr into the same file:

nohup [Command here] > filename.out 2>&1 &

The first > redirects stdout to filename.out, 2> corresponds to the stderr which is redirected into the same place as stdout &1 and the final & returns you to the terminal immediately, ready for the next command.
