[Vala] Terminal output in a text file



Hi, i am new in Vala Programation.
I have a problem using the comand  "Process.spawn_command_line_sync" : when
i try to set a comand similar to " ls > text.txt" the program doesn't
create the txt file requested.
I will post u an example code to make this clearer to you.

[CCode (instance_pos = -1)]
public void on_combobox2_changed (ComboBox source){
Process.spawn_command_line_sync ("ls > text.txt");
}

Why the txt file is not generated.can you explain it to me please?
Thank you for the time you are spending on my request of help.
