#
# this expect snipit is sourced by clogin (-s option) to issue a reload
# command on a cisco router. it DOES NOT save the config if it has been
# modified. this is an _example_ as it not guaranteed to work for all
# applications. PLEASE test for your environment.
#
# it expects the following variables via the -E option:
# reload_arg ='command argument' such as 'at 05:00' or 'cancel
#
# eg usage:
# % clogin -s cisco-reload.exp -Ereload_arg='at 01:00' router
# router
# Reload scheduled for 01:00:00 UTC Sat Jun 23 2001 (in 7 hours and 16 minutes)
# % clogin -s cisco-reload.exp -Ereload_arg='at cancel' router
# router
# % Ambiguous command: "reload at cancel"
#
# % clogin -s cisco-reload.exp -Ereload_arg='cancel' router
# router
# SHUTDOWN ABORTED
#
#
# keep in mind that it is important to NOT polute the global variable space.
# particularly, do not use variables used within clogin. this may result in
# indeterministic results. an easy way to avoid this is to use a variable
# name prefix (like 'E' or '_').
#
# useful variables from clogin global space:
# router router name as provided on the cmd-line
# prompt cmd-line prompt as determined by clogin
#
# note: the tcl/expect parser is extremely stoopid. comment lines are NOT
# completely ignored!! so, a '{' or '}' in a comment might produce
# unexpected results.
