This class is used to create operating system processes.

# 1 Running a process

In Javascript, we can use ProcessBuilder to call external commands easily. In the following example we see how an external ls command (using bash), and display the output.

Copy
<script>
var pb = new Ax.lang.ProcessBuilder();
var status = pb.directory('/tmp').command('/bin/bash', '-c', 'ls -l');
if (status == 0)
console.log(pb.getStdOut());
else
console.log(pb.getStdErr());
return status;
</script>

# 2 Non blocking process

The process.getInputStream is “blocking” so it will block main thread until process completed. In the case we want to run with a timeout to avoid a long running process hangs the script application you can use a timout value.

To set a timeout use setTimeout(int second) in process builder object.
