In this article, we will make a simple bot logger. This script will log a few channels as well as handle the pings.
Prerequisites
Besides having a Terminal open, you need to have basic knowledge of IRC.
Write script:
Now, we will write a script for an IRC logging bot. Create the logging_bot.sh script and write the following code in it:
logging_bot.sh
#!/bin/bash
nick="blb$$"
channel=testchannel
server=irc.freenode.net
config=/tmp/irclog
[ -n "$1" ] && channel=$1
[ -n "$2" ] && server=$2
config="${config}_${channel}"
echo "NICK $nick" > $config
echo "USER $nick +i * :$0" >> $config
echo "JOIN #$channel" >> $config
trap "rm -f $config;exit 0" INT TERM EXIT
tail -f $config | nc $server 6667 | while read MESSAGE
do
case "$MESSAGE" in
PING*) echo "PONG${MESSAGE#PING}" >> $config;; *QUIT*) ;;
*PART*) ;;
*JOIN*) ;;
*NICK*) ;;
*PRIVMSG*) echo "${MESSAGE}" | sed -nr "s/^:([^!]+).*PRIVMSG[^:]+:(.*)/[$(date '+%R')] \1> \2/p";;
*) echo "${MESSAGE}";;
esac
doneHow script works
In this script, we handled the pings; also, we are logging some channels.
