In this blog post, we will describe some of the possible causes that runtime.exec commands can cause, and then I will suggest possible solutions to this problem.

The exec method (String command), as you can see, is executing the specified String command in a complex process. This is the formula for comfort. The call to the intermediate exec (command) behaves in exactly the same medium as the call to exec (command, null, null).

Description

A launch command expression is a command generated from other commands and / or programs, such as MEL commands, Maya requirements, MEL procedures. Think of the learning command as a “one-word wrapper” and an alias that really allows you to run scripts (or series of scripts) after the MEL command line with a better abbreviation.

java.lang.Runtime.exec (string comanda) means the specified string command will be executed while the process is disabled. This will be a practical method. Calling a specific form exec (command) usually behaves exactly like calling exec (command, null, null).

Explanation

public Process Exec (string command)

Parameters

Return Value

The exec (String [] cmdarray, String [] envp) method executes the receive and arguments specified in the individual methods against the specified environment. This is a very practical method. A call with the form exec (cmdarray, envp) behaves exactly like its call exec (cmdarray, envp, null).

This method returns a new process idea to control the subprocess
