title: get only a COMMAND column in cygwin for ps command
body: <p>In Cygwin, I can get the list of running processes by following command:</p>
  
  <pre><code>      PID    PPID    PGID     WINPID   TTY         UID    STIME COMMAND
      13160       1   13160      13160  ?         197609 13:42:18 /usr/bin/mintty
  S   15404    2852   15404      16776  pty2      197609 13:59:29 /usr/bin/vi
       2852   12912    2852      11244  pty2      197609 13:42:54 /usr/bin/bash
       9864       1    9864       9864  ?         197609 13:11:32 /usr/bin/mintty
  S   10500    2852    1692       1452  pty2      197609 14:09:42 /usr/bin/less
  S   17644    2852   17644      11880  pty2      197609 14:00:15 /usr/bin/vi
      12912       1   12912      12912  ?         197609 13:42:54 /usr/bin/mintty
       8432    2852    8432      12020  pty2      197609 14:10:05 /usr/bin/ps
      17092   13160   17092      14720  pty1      197609 13:42:18 /usr/bin/bash
  </code></pre>
  
  <p>However, I just want the <code>COMMAND</code> column but not all columns like this:</p>
  
  <pre><code>COMMAND
  /usr/bin/mintty
  /usr/bin/vi
  /usr/bin/bash
  /usr/bin/mintty
  /usr/bin/less
  /usr/bin/vi
  /usr/bin/mintty
   /usr/bin/ps
  /usr/bin/bash
  </code></pre>
  
  <p>In MAC, I can do this by the following command:</p>
  
  <pre><code>ps -o command
  </code></pre>
  
  <p>The same command is not working for cygwin in windows because the <code>-o</code> option is not there in ps for cygwin.</p>
