Apple

Hi all,

I am using packageMaker for installing my application. Before starting installation I need to verify whether application is currently running at user’s machine or not, if YES then stop installation.

Inside InstallationCheck script which is a Perl script I have called a shell command to check for running status of my application.

The part of script is like this:

$output = `ps aux | awk '/MyAPP/ && !/awk/ {print $2}'`;

if($output)

{

$EXIT_VALUE = (113);

last;

}

This particular scripts runs properly when executed from command line but while it runs with installer no output comes for this part of script whereas other part of script like os version check run properly with installer.

What may be the reason that script segment is not working with installer?

Does it has something to do with super user or current user privileges?

How to solve it?

Please help me.

Thanks,

Manish
