receiverc

这是一个同样来自贝尔实验室的和UNIX有着渊源的操作系统, 其简洁的设计和实现易于我们学习和理解

#!/bin/rc

# Arguments should be
#	time Y|N pages [ftsi]

switch($#*){

case 4
	#
	# Check for the NYT. It's 9 pages from
	# area-code 202.

	if(~ $2 Y && ~ $4 20240*){
		if(~ $3 9){
			for(i in 001 002 003 004 005 006 007 008 009){

	}
	if not
		echo FAX: page $spool/$1.* | mail `{cat $recipients}
case 3
