|Short description||Execute commands in parallel on the local host or on remote hosts|
|Full description||The main purpose of the program `pexec` is to execute the given command or shell script (e.g. parsed by /bin/sh) in parallel on the local host or on remote hosts, while some of the execution parameters, namely the redirected standard input, output or error and environmental variables can be varied. This program is therefore capable to replace the classic shell loop iterators (e.g. for ~ in ~ done, in bash) by executing the body of the loop in parallel. Thus, the program `pexec` implements shell level data parallelism in a barely simple form. The capabilities of the program is extended with additional features, such as allowing to define mutual exclusions, do atomic command executions and implement higher level resource and job control.|
