how to get certain columns from ps aux
<p>Im using ps aux to ouput the top 10 processes on my computer sorted by memory. This is the command that I have:</p>

<pre><code>ps aux --sort %mem --cols 100 |tail -10
</code></pre>

<p>This outputs something like</p>

<pre><code>USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

<p>Is there any way I can get rid of some of the columns? I only want that User, pid, %mem and command.</p>

<p>Thanks!</p>
