Perl script: different results form command line and CGI

Warning: I'm perl and CGI beginner so this can be stupid question.

I write a really simple perl script which should get info about open files and running processes on system. There is something like this function for processes:

sub num_processes() {
    my @lines = `/bin/ps -ef`;
    return scalar @lines;
}

If I run it from bash, it returns all running processes on system but when I run it via apache and CGI it retruns only 2 processes (running script and running 'ps -ef'). This CGI script runs under user with shell (/bin/bash) enabled. Is there any posibility how to get all the processes via apache and CGI?

Your CGI script will run as the Apache user account. Your shell call will run as your user account. This is probably why you get two different answers. Take a look at something like suEXEC to manage the user under which CGI scripts are run.
