Can you run UNIX commands in a Python or Java Program?

[digitalzero]

I was just wondering whether you could run UNIX commands like:
"clear" or "ls" in Python programs or Java programs.
Anyone know how?

i run them in PHP (executed serverside and the results posted on the webpage.)
prolly not what your after though.
e.g to give a size of my entire website i put this in my page:

<?php echo $size =shell_exec("du -sh ../htdocs") ?>

see http://zion.alturl.com in the stats section for tricks i've done with PHP like this.

yes, you can in both:

For Java, see the Runtime.exec method, for example you might do something like:

Runtime rt = Runtime.getRuntime();
Process lsProcess = rt.exec("ls -l");
... and so on

For Python, something like:

import os
retCode = os.system("ls -l")
... and so on

In Python you simply:

>>>import os
>>>os.system('vi')

Will launch the vi editor.

Hope it helps,
