Good afternoon dear Monks,
I'm attempting to search logs using tail -f so if the specific string got into the log file we should print the first 3 occurrences and continue the rest of the script, but it is not working. The strings passed as a commandline argument.
I appreciate the your valuable input
use warnings;
use strict;
my $currentDate = `date +%Y%m%d`;
my $logPath = "/dhcp/logs"
my $logFile = "{$path}/DHCPD.log.{$currentDate}"
my @tail = qx(tail -f -1 $logFile | grep $_);
if (@tail) {
print @slice = @tail[0 - 2];
last;
}
else {
print "not found";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
