Hi,
I'm looking for a perl script or program that can interact with my cs source server from the commandline. I would use it in scripts to check stuff.
I need it for Linux, but it would be nice to have for windows also.
Thanks, it would really be cool!!!

Not sure about a Perl script, but I've been using this C program to graph player connections:
Quote:/*
# This is a simple linux command line utility to execute rcon commands
# Just change the YOUR_PASSWORD_HERE to your rcon password (unless
# you want to enter it every time) and possibly change the default
# IP address from 127.0.0.1 (localhost)
#
# once downloaded on your linux system, compile it with:
#
# gcc -o rcon rcon.c
#
# note, it should work on non-linux too, but may require changing the
# socket stuff (i.e. windows will definitely need to add the winsock
# initialization line)
