For example, I have an executable called ex01 (C++ program).And I have a text file that contains a set of invocations of this program with different arguments.The text file looks like this:./ex01 command1 > ex.dat  &./ex01 command2 >> ex.dat &./ex01 command3 >> ex.dat &...I can use the source command to do this task automatically.But I was hoping to do this in parallel. How can I do that?
How to use the source command to run commands simultaneously?
command line
