Now, we will write a script for an IRC logging bot. Create the logging_bot.sh script and write the following code in it:
#!/bin/bashnick="blb$$"channel=testchannelserver=irc.freenode.netconfig=/tmp/irclog[ -n "$1" ] && channel=$1[ -n "$2" ] && server=$2config="${config}_${channel}"echo "NICK $nick" > $configecho "USER $nick +i * :$0" >> $configecho "JOIN #$channel" >> $configtrap "rm -f $config;exit 0" INT TERM EXITtail -f $config | nc $server 6667 | while read MESSAGEdo case "$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}";; esacdone
