Extract Numbers from a log file
Hi,

I am trying to grep/extract the number list from this log file, can I get some help on this. I can grep the word 'href' to see the numbers, but it is resulting with the complete line.

Content of my file:
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<html>
<head>
<title>Index of Directory/Temp</title>
</head>
<body>
<h1>Index of Directory/Temp</h1>
<pre>Name  Last modified      Size</pre>
<hr/>
<pre><a href="https://www.unix.com/">../</a>
<a href="129/"">129/</a>   22-Aug-2013 10:00    -
<a href="133/"">133/</a>   21-Aug-2013 14:04    -
<a href="134/"">134/</a>   21-Aug-2013 14:10    -
<a href="135/"">135/</a>   21-Aug-2013 14:12    -
<a href="136/"">136/</a>   21-Aug-2013 14:15    -
</pre>
<hr/>
<address style="font-size:small;"> Server at Test Port 80</address>
</body>
</html>

Expecting output is :
Code:
129
133
134
135
136

This solution is not so generic. Works fine if all the numbers are three digit numbers.

Code:
awk -F">" '/^<a href/{print substr($2,1,3)}' filename

Try:
Code:
awk '/^a href/{sub("/",x,$2); print $2}' RS=\< FS=\> file

Code:
..
129
133
134
135
136

Which three-digit-number do you want, the first or the second?
Code:
sed -rn '/a href/ s/^[^"]*"([0-9]{3}).*$/\1/p' file
129
133
134
135
136
