voidpassthru(string $command[,int&$return_var]) Thepassthru()function is similar to the exec() function in that it executes acommand. This function should be used in place of exec() or system() when the output from the Unix command is binary data which needs to be passed directly back...

That’s where exactly the "kill process Linux" command comes in handy. This command is used in Linux and other Unix-based systems to stop programs. Using this command, you’ll send a message to the operating system to stop that program. How does it work? Just like every person has a...

Like the JavaProcessBuilder, NuProcess offersNuProcessBuilder, so building a process is fairly simple. Let's make a simple example where we use the Unix "cat" command. When launched with no parameters,catreads from STDIN and echos the output to STDOUT. We're going to start thecatprocess, ...
Unix's time command recursively records the CPU time consumed by the child processes created by the parent process if the parent process waits for its child processes. However, whether the parent process waits or not, Windows's GetProcessTimes does not record any CPU time consumed by the child...
