Exec

Do you mean:

• The exec command, /exec [options] command, which manages asynchronous subprocesses and integrates their output with the client's event loop?
• The exec function, $exec(program [arguments...]), which directly launches a program and returns three EPIC file handles for its input, output, and error streams? These pipes are blocking and are separate from command-managed process references.

Related interfaces are execctl, for command-managed process descriptions, and on exec, for stdout lines from those processes. Standard error and termination use exec_errors and exec_exit.

The command normally uses the configured shell unless direct execution is selected. The function does not implicitly use a shell. Both run local programs; output reaches IRC only when explicitly directed there. Consult the selected interface for quoting, callbacks, results, and cleanup.
