<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I have files with the following structure:<br>
<br>
garbage<br>
garbage<br>
garbage<br>
output start<br>
.. good data<br>
.. good data<br>
.. good data<br>
.. good data<br>
output end<br>
garbage<br>
garbage<br>
garbage<br>
<br>
How can I extract the good data from the file trimming the garbage<br>
from the beginning and end?<br>
<br>
The following works just fine but it's dirty because I don't like the<br>
fact that I have to pick an arbitrarily large number for the "before"<br>
and "after" values.<br>
<br>
grep -A 999999 "output start" <infile> | grep -B 999999 "output end" > newfile<br>
<br>
Can anyone come up with something more elegant?<br>
