Hi, i am a new member,

and as the question's title says i would like to execute a system call but instead getting the display of the command in the console i want to have a .txt file created or be able to get the output of the file created by this system call.

$var = `<my command> 2>&1 1>/dev/null`;

i still had the output of the command, then

open FILE, "<my command> 2>&1 1>/dev/null" or exec(); die $!;

and system("<my command> 2>&1 1>/dev/null");

i still had the output of the command in the console. I started perl a week ago and i think i am taking the wrong approach on this problem, could you please help me ?

*update* changed the question's name

I done additional research on the command i would like to run, and found out that the command write a file that i can use so the retrieving output problem is solved but i still can cancel the display of the command

Additionally as X-mas is coming I'd like to know what books or tutorials should I read about using perl to monitor and manage external process on Linux or something nice to start. Thank you.

Regards

Thank you all for your answers i now understand my mistakes

Actually, my command couldn't execute without outputting a display so I did it in a separate terminal ... The structure i used for this purpose is :

sub sigtrap() {
    if(defined($pid) && ! ($pid == 0)){
        killfam 'TERM', ($pid);
    }
    print "\n";
    exit(1)
}
$pid = fork();
if($pid == 0){
    #print "DEBUG - I am the child pid : $$ \n";
    qx/my command running in background 2>&1 1>\/dev\/null/;
    sleep 10;
    exit(0);
}
sleep 15;
#use the command's output file to get the results
