Abstract
A shell control program 401 is deployed on a controlling computer 402 of a distributed computer system. The shell control program reads commands input from a command source, either user input or script, and passes this input to a parser which generates parsed code for execution by shell slave processes 404. The shell control program also determines which shell slave processes are required to execute a command. This may involve a plurality of shell slave processes on a plurality of machines or a single machine. Once the shell control program has identified the type and location for the required shell slave processes it determines if the required shell slave processes are already present in the system and if not creates them. Instructions for executing parts of the command are then distributed to the identified shell slave processes to complete the execution and return results to the shell control program. The shell control program can be completely platform independent using JAVA. Each of the shell slave processes can have multiple input and output data streams routed directly or indirectly between processes in the network. Pseudo terminal instances (507, figure 5) may be set up by the shell slave processes allow command processes (501, 502, 503) to be processed on remote computers as they would be had they been executed on the controlling computer.
