To capture output of shell command in ansible variable use:
<pre>
    - shell: ifconfig | grep mtu | grep [ep][n0-9]p[0-9] | sed 's/:.*$//g'
      register: ifconfig_output
</pre>

Here register is a variable name which will capture exit status, output, etc.  For accessing the output use:
<pre>
    - name: Disable management of p2p1 by network-manager
      shell: "echo NM_CONTROLLED=no >> /etc/sysconfig/network-scripts/ifcfg-{{ifconfig_output.stdout}}"
</pre> 
The output can also be used in a template such as:
<pre>
dhclient -v {{ifconfig_output.stdout}}
</pre>

Thus, ifconfig_output is a dictionary and output is stored in stdout.  Other things stored in ifconfig_output register can be found using 
<pre>
- debug msg="{{ifconfig_output}}"
</pre>
