Im using ps aux to ouput the top 10 processes on my computer sorted by memory. This is the command that I have:
ps aux --sort %mem --cols 100 |tail -10
This outputs something like
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
dmak1112 3564 0.0 1.2 831788 104588 ? Sl 12:59 0:01 /opt/google/chrome/chrome --type=re

Is there any way I can get rid of some of the columns? I only want that User, pid, %mem and command.
Thanks!
aux is not actually a secret password to make ps let you in. It's a set of options specifying which processes (a and x) and fields (u) you want.
man ps describes those and other options you can use. In your case:
ps -eo user,pid,%mem,command --sort=%mem
