# 	WAKibbe@nwu.edu
#
# version 1.0 release 2
# Changes 9/26/96. 
# - Script is no longer path dependent.
# - run under the "sh" shell
# - pass to it the subnet to be 'ping'ed in the command line
#     : sh ping.sh 129.1.1
# - may need exact path for crontab entry
#     : 54 08 * * 5 sh /user/myhome/ping.sh 129.105.72 
#         runs at 08:54 every friday
