run() Netscript Function

run(script[, numThreads=1[, args...]])
RAM cost:

1 GB

Arguments:
  • script (string) – Filename of script to run
  • numThreads (number) – Optional thread count for new script. Set to 1 by default. Will be rounded to nearest integer.
  • args... – Additional arguments to pass into the new script that is being run. Note that if any arguments are being passed into the new script, then the second argument numThreads must be filled in with a value.
Returns:

The process id of the new process or 0 on failure.

Run a script as a separate process. This function can only be used to run scripts located on the current server (the server running the script that calls this function).

Warning

Running this function with a numThreads argument of 0 or less will cause a runtime error.

The simplest way to use the run command is to call it with just the script name. The following example will run foo.script single-threaded with no arguments:

run("foo.script");

The following example will run ‘foo.script’ but with 5 threads instead of single-threaded:

run("foo.script", 5);

This next example will run foo.script single-threaded, and will pass the string foodnstuff into the script as an argument:

run("foo.script", 1, 'foodnstuff');
