Subject: System
About that PID problem, i found a program in Windows named tasklist,
it prints all the processes running on the system with its id. I used
the system command to execute the tasklist, like as
my $data = system "tasklist" ;
but i got nothing in $data. How can i get the data from the system
command?
Hi Somu
You can't capture data with 'system'.
From the documentation for system:
This is not what you want to use to capture the output from a command, for
that you should use merely backticks or qx//, as described in `STRING` in
the perlop manpage. Return value of -1 indicates a failure to start the
program or an error of the wait(2) system call (inspect $! for the reason).
