Hi everyone. I am trying to write a simple shell interpreter. And I want it to act like bash, i.e. when user wants to run a process in the background, and the process tries to access stdin or stdout, the shell sends it SIGTTOU. So, I write: 
...
$pid = fork()
if($pid == 0)
{
    if($command =~ /\&$/) 
    {
        if(-t STDIN and -t STDOUT)
        {
           kill TTOU =>$pid;
           exec($command);
        }
    }
    else 
    {
        ...
    }
}

As I expect, it kills the forked process without executing the command. Can anyone help me with the problem?

thanks in advance, anna.
