from text file to web page

tepok · Jun 3, 2003

I have a constantly updating text file (a log file), and I'd like to see it on a web page in almost real time. So what I need is a script which echoes the text file to html (perhaps tail, i use linux) and then autorefresh to the page.
I am sure this is a trivial task for you who are experienced but I have not yet managed to get anything useful done, so any help is greatly appreciated.

I think this is close....' have not tried to run it.... ;-)

Code:

#!/usr/bin/perl
use strict;
use CGI;
use CGI::Carp 'fatalsToBrowser';

my $cgi = new CGI;
my $url = $cgi->url();

print $cgi->header,
      qq(<head>
         <meta HTTP-EQUIV=&quot;REFRESH&quot; 
         CONTENT=&quot;10;  url=$url&quot;>
         </head><body><p>);
         
my @records = `tail -100 /path/to/log/file.txt`;
foreach (@records) { print &quot;$_<br />\n&quot;; }

print qq(</p></body></html>);

There may be a typo or two.... hopefully it'll get you headed in the correct direction. Note that those are not quotes around the 'tail' command, they are backticks (below the ~ on the keyboard). Also, you'll need to modify the path and name of the log file to read. The 'CONTENT: 10' tells the page to refresh every 10 seconds.

'hope this helps
