node-core-library.executable.spawn

Executable.spawn() method

Start a child process.

Signature:

static spawn(filename: string, args: string[], options?: IExecutableSpawnOptions): child_process.ChildProcess;

Parameter	Type	Description
filename	string	The name of the executable file. This string must not contain any command-line arguments. If the name contains any path delimiters, then the shell's default PATH will not be searched.
args	string[]	The command-line arguments to be passed to the process.
options	IExecutableSpawnOptions	(Optional) Additional options

Returns:

child_process.ChildProcess

the same data type as returned by the NodeJS child_process.spawnSync() API

This function is similar to child_process.spawn(). The main differences are:

It does not invoke the OS shell unless the executable file is a shell script. - Command-line arguments containing special characters are more accurately passed through to the child process. - If the filename is missing a path, then the shell's default PATH will be searched. - If the filename is missing a file extension, then Windows default file extensions will be searched.

This command is asynchronous, but it does not return a Promise. Instead it returns a Node.js ChildProcess supporting event notifications.
