NAME
     waitfor - wait for	a string to appear on the stdin

SYNOPSIS
     waitfor [ -n ] string

DESCRIPTION
     Waitfor reads the standard	input and  returns  a  0  if  the
     string argument is	found, returns a 1 if the strings did not
     appear within the allotted	time, or returns a -1  on  error.
     If	the string is found, waitfor returns immediately.

     Waitfor is	designed to be	used  by  Pcomm	 inside	 a  shell
     script  for  automating  keyboard input to	log a user onto	a
     remote system.

     The -n option is used to  specify	the  length  of	 time  in
     seconds to	wait.  The default is 10 seconds.

EXAMPLE
	  # wait 5 seconds for the login prompt
	  waitfor -5 login:
	  # test the exit code of the waitfor command
	  if [ $? -eq 0	]
	  then
	       # send my user ID
	       echo egray
	  fi
