```sh
exec command [args]*
output = exec command [args]*
stdout = set ${output.stdout}
stderr = set ${output.stderr}
exit_code = set ${output.code}
```
Executes the provided native command and arguments.<br>
If no output variable is set, the command output will be flushed to the main out/err stream of the parent process.<br>
If an output variable is set, it will be used as a base variable name from which the command stout, stderr and exit code information can be pulled from.<br>
The actual output variable name will not be modified, instead new variables will be created using that variable name as a baseline:
* *output*.stdout - Will hold the stdout text content.
* *output*.stderr - Will hold the stderr text content.
* *output*.code - Will hold the process exit code.
#### Parameters
The command to execute and its arguments.
#### Return Value
Optionally a base name to access the process stout, stderr and exit code information.
#### Examples
```sh
# Example of running a command and flushing its output to the parent process.
exec echo hello world
# Example of running a command and storing its output.
output = exec echo hello world
stdout = set ${output.stdout}
stderr = set ${output.stderr}
exit_code = set ${output.code}
echo stdout: ${stdout}
echo stderr: ${stderr}
echo exit code: ${exit_code}
```
