So I'm afraid it is not what you are looking for.

There is also the Context.RunScript operation, but it is to manipulate the context variables with a script, not to run shell commands.

A solution would be to create your own Nuxeo operation where you run your shell commands with something like this:

Process p = Runtime.getRuntime().exec("shell command")

You can also set the shell command as a operation parameter.
