If you have sufficient ram, you could have nawk read the tempfile once, when it starts, store its lines in an array, and then read the IDs from standard input. For each ID you can then iterate through the tempfile array and check for matches. This way, you don't have to create a new nawk process for each loop iteration nor do you have to read the file in its entirety once for each $x (even if the file's contents are cache'd by the operating system, it still requires a syscall for each read).

smokeping_cgi

SMOKEPING_CGI(1)						     SmokePing							  SMOKEPING_CGI(1)

NAME

       smokeping_cgi - SmokePing webfrontend

OVERVIEW

       This script acts as a 'website' for your SmokePing monitoring operation. It presents the targets you are looking at in a tree structure and
       draws graphs as they are required by people looking at the pages.

DESCRIPTION

       To get smokeping_cgi going, you need a webserver which allows you to run CGI or better FastCGI scripts. The system must be setup so that
       the cgi process is allowed to write to the image caching area as defined in the config file.

       This script runs fine as a normal CGI, BUT it will appear to be very slow, because it does a lot of things when starting up. So if the
       script has to be started a fresh on every click, this is both slow and a tough thing for your webserver. I therefore strongly recommend
       using FastCGI.

       Please refer to the installation document for detailed setup instructions.

SETUP

       There is a sample htdocs directory in your smokeping installation root.	Copy its content to the place where your webserver expects its
       files.  There are also two sample cgi scripts showing how to launch the smokeping cgi in your website. The only difference is the file
       extension.  Adjust the paths in the script and you should be ready to go.
