Important: The process package has been deprecated. Use the superseding package Threads instead.

The kill command kills one or more processes that were created with fork.

This can be useful if several child processes were created to work in parallel, one has completed, and the rest are to be terminated.

kill can also be used to kill other processes if one knows their process IDs.

The kill function is only available on platforms that support true concurrent processing (for example, UNIX).

The command with(process,kill) allows the use of the abbreviated form of this command.
