in thread viewing log via HTML

Don't forget to encode your data. Angle brackets in the log file will make life miserable otherwise.
#!/usr/bin/perl -w use CGI; use strict; use HTML::Entities; my $query = new CGI; print $query->header(), $query->start_html(-title=>"My log file"), $query->h1('Tail'); # put your tailing method here while (1) { while (my $input = <INPUT>) { $input .= '<br/>'; print encode_entities( $input ); } sleep $delay_period; seek(INPUT, 0, 1); } print $query->end_html();

Cheers,

    I tried this and it doesn't seem to load. I don't get any errors, it just keeps "waiting for a response". I took any html calls out and it worked fine to a term. Any ideas are appreciated.
      If you have checked your logs and are not getting an error, perhaps you need to unbuffer your output. Add $|++; to the top of the code:
      #!/usr/bin/perl -w use CGI; use strict; use HTML::Entities; $|++;
      For more information, see Suffering from Buffering.

      Also, try running the from the command line to see what the output is. Frankly, I didn't look at the code too closely. I just saw data being dumped to the screen that wasn't encoded and responded to that. Good luck!

      Cheers,
