This shell script can come in handy for updating files on multiple
machines in 4.2BSD networked environments. It's no substitute for a
real remote file system, but it gets the job done . . . . All you need
to do to it is edit the default list of machines.

# rrcp - do a complete rcp (to all local machines)

# This code is careful not to invoke extra programs for non-sysV "sh"s
