Assuming your event starts with someting like &quot;Event ID 99&quot; and ends with someting like &quot;Event END&quot; you can do<br />
<br />
awk '/Event ID 99/,/Event END/' logfile<br />
<br />
wmp
</div>


Assuming your event starts with someting like "Event ID 99" and ends with someting like "Event END" you can do

awk '/Event ID 99/,/Event END/' logfile

wmp

<div>
... and there is also Perl:<br />
<br />
perl -ne 'print if /Event ID 99/../Event END/' logfile<br />

</div>


... and there is also Perl:

perl -ne 'print if /Event ID 99/../Event END/' logfile


<div>
it would be interesting to know the timing results on such a large file from the 3 methods suggested by wmp, if you get a chance.

Experts ! &nbsp;I am a linux newbie &nbsp;. I have a large log file whcih is around 2.5 GB on a linux server. I want to search for an event &nbsp;which got only few lines of text within that log file . How can I search or extract that event from that log file .<br />
I &nbsp;am afraid to open this log file with text editors like vi or nano directly from the server since it is in production. i will be in trouble if my server &nbsp;freezes.

Extarcting some text from linux log file

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.

Linux Security

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.

Linux OS Dev

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
