[Tutor] script question

[Chris Hallman]

Here is my latest revision, which works very well.

# This Python script was written to forward interface down messages
# to ESM1. If the incoming arguements match the interface file
# (c:\utils\interface.ini) then the message is forwarded.
#
# Author: tcdh
# Date: 09/22/05
# Modified: 10/04/05 changed os.system to use raw("r") strings. Used % and
join method to join
# the sys.argv's. replaced list generating lines with one line of code.
#


import ConfigParser, sys, os
section = sys.argv[1]
interface = sys.argv[3]
ini=ConfigParser.ConfigParser()
ini.read("c:\utils\interfaces.ini")
interface_list=ini.items(section)
for i in interface_list:
if i[1] == interface:
os.system(r"d:\tnd\bin\delkeep.exe -all -n l17aesm1 %s" % ("
".join(sys.argv[1:3]),)+
"*")
os.system(r"d:\tnd\bin\cawto.exe -cat NetNet -n l17aesm1 forward red held
%s" % (" ".join(sys.argv[1:5]),))
break


Again, thank you all for your input. I greatly appreciated it!!!! Let me
know if you have any further suggestions.
