Hi there,<br />
<br />
I am trying to grep my access log to remove all MSIE and Mozilla lines..<br />
<br />
If I do<br />
bash$ tail -f access.log | grep -v 'MSIE'<br />
then I exclude all MSIE no problem.<br />
but if I change it so <br />
'MSIE|Mozilla'<br />
or<br />
&quot;MSIE|Mozilla&quot;<br />
or<br />
even try both with &quot;(MSIE|Mozilla)&quot;<br />
then it will just show all as usual...<br />
how can I use grep to exclude MSIE and Mozilla <br />
thinking about it now... the | = or so that with -v might be my downfall...

Grep with OR and -v
