Eggdrop 1.9.2 documentation

Last revised: May 5, 2021

# README

> Please, at least SKIM this document before asking questions. In fact, READ IT if you’ve never successfully set up an Eggdrop bot before.

## NOTICE

> Make SURE that you select your +n (owner) users wisely. They have 100% access to your bot and account. ONLY GIVE THIS POWER TO SOMEONE YOU TRUST COMPLETELY!

## What is Eggdrop?

> Eggdrop is the world’s most popular Internet Relay Chat (IRC) bot; it is freely distributable under the GNU General Public License (GPL). Eggdrop is a feature-rich program designed to be easily used and expanded upon by both novice and advanced IRC users on a variety of hardware and software platforms.

> An IRC bot is a program that sits on an IRC channel and performs automated tasks while looking just like a normal user on the channel. Some of these functions include protecting the channel from abuse, allowing privileged users to gain op or voice status, logging channel events, providing information, hosting games, etc.

> One of the features that makes Eggdrop stand out from other bots is module and Tcl scripting support. With scripts and modules you can make the bot perform almost any task you want. They can do anything: from preventing floods to greeting users and banning advertisers from channels.

> You can also link multiple Eggdrop bots together to form a botnet. This can allow bots to op each other securely, control floods efficiently and even link channels across multiple IRC networks. It also allows the Eggdrops share user lists, ban/exempt/invite lists, and ignore lists with other bots if userfile sharing is enabled. This allows users to have the same access on every bot on your botnet. It also allows the bots to distribute tasks such as opping and banning users. See doc/BOTNET for information on setting up a botnet.

> Eggdrop is always being improved and adjusted because there are bugs to be fixed and features to be added (if the users demand them and they make actually sense). In fact, it existed for several years as v0.7 - v0.9 before finally going 1.0. This version of Eggdrop is part of the 1.9 tree. A valiant effort has been made to chase down and destroy bugs.

> This README file contains information about how to get Eggdrop, command line options for Eggdrop, what you may need to do when upgrading from older versions, a list of frequently asked questions, how to set up a crontab, some boring legal stuff, some basics about git usage and some channels where you might get help with Eggdrop.

## HOW TO GET EGGDROP

> Before you can compile Eggdrop, you need to have Tcl installed on your system. Most systems should have Tcl on them by now - you can check by trying the command “tclsh”. If it works, you will be given a “%” prompt and you can type “exit” to exit the program. This means Tcl is installed on your system. If tclsh doesn’t load, then Tcl probably isn’t on your system, and you will need to install it. The website to download Tcl is https://www.tcl.tk/software/tcltk/download.html and most OS distros have a binary installation available. If installing via an OS package manager, make sure to install the development library as well, usually called something similar to ‘tcl-dev’.

> Currently, the 1.9 tree of Eggdrop is developed at eggheads.org. You can get the latest STABLE version of Eggdrop from the following url:

> > https://geteggdrop.com/

> You might try www.eggheads.org for help and information.

## Git Usage

> Eggdrop development has moved from a CVS-based version control system to git. If you are interested in trying out the VERY LATEST updates to Eggdrop, you may be interested in pulling the most recent code from there. BE WARNED, the development branch of Eggdrop is not to be considered stable and may (haha) have some significant bugs in it. The Eggheads Development Team will in NO WAY take any responsibility for whatever might happen to you or your shell if you use the development branch of Eggdrop!

> To obtain Eggdrop via the git repository (hosted by GitHub), you can either clone the repository via git or download a development snapshot.

> To clone the repository, simply type:

>     git clone https://github.com/eggheads/eggdrop.git

> Otherwise, you can download the development snapshot as a tar archive from:

> > https://github.com/eggheads/eggdrop/archive/develop.tar.gz

## Quick Startup

> Please, see the INSTALL file after you finish reading this file.

## Upgrading

UPGRADING FROM AN OLDER 1.3/1.4/1.5/1.6/1.8 TO A 1.9 VERSION

> If you followed the INSTALL file and did a ‘make install’ (or ‘make install DEST=”path”’) after ‘make’, this will be pretty easy. Just upload the new eggdrop-1.9.x.tar.gz file to your home dir on your shell, gunzip and untar it, and type ‘cd ~/eggdrop-1.9.x’. Next, type ‘./configure’, ‘make config’ or ‘make iconfig’, then ‘make’. Then, kill the bot (‘.die’ on the partyline) and ‘make install’ to the same directory your bot is currently in. After that, you can just restart your bot. You may wish to delete the old Eggdrop executable and modules as well, especially if you have limited disk space.

> You should read through the new eggdrop.conf file for all of the new options in Eggdrop 1.9.x. You can copy and paste any of these settings into you current conf file if you do not want to use the default settings.

## Command Line

> Eggdrop has some command line options - not many, because most things should be defined through the config file. However, sometimes you may want to start up the bot in a different mode and the command line options let you do that. Basically, the command line for Eggdrop is:

>     % eggdrop [options] [config-file]

> The options available are:

> > -t: Don’t background, use terminal. Your console will dropp into an
> >   interactive partyline session, simialar to a DCC chat with the bot. This is useful for troubleshooting connection issues with the bot.
> > -c: Don’t background, show channel info. Every 10 seconds your screen
> >   will clear and you will see the current channel status, sort of like “top”.
> > -m: Create userfile. If you don’t have a userfile, this will make Eggdrop
> >   create one and give owner status to the first person that introduces himself or herself to it. You’ll need to do this when you first set up your bot.

> > -h: Show help, then quit.

> > -v: Show version info, then quit.

> Most people never use any of the options except -m and you usually only need to use that once.

## Setting up a Crontab

> Eggdrop has become more stable with time, thanks mostly to people reporting bug details and helping find places where it crashes. However, there are still a -few- places where things aren’t perfect. Few, if any, things in life are.

> Also, most systems go down from time to time. These things cause your bot to disappear from IRC and you have to restart it.

> Eggdrop comes with a shell script as scripts/botchk that will help keep the bot online. It will make the machine check every ten minutes to make sure your bot is still running. To use it, you have to add a line to your crontab. First, edit ‘botchk’ and change the directory and command line parameters so that it will be able to start up your bot. Then, add this line to your crontab:

>     0,10,20,30,40,50 * * * * /home/mydir/botchk

> If you don’t want to get emails from cron, use this:

>     0,10,20,30,40,50 * * * * /home/mydir/botchk >/dev/null 2>&1

> Naturally, you need to change the path to the correct path for botchk. If you’ve never used crontab before, here is a simple way to add that line:

> > 1. Create a new file called ‘mycron’ and put the above line into it;
> > 2. From your shell prompt, type ‘% crontab mycron’.

> That will create a new crontab entry for you with a line that runs botchk every ten minutes. Botchk will then restart the bot when necessary (and send you email informing you).

## Setting up a Crontab using autobotchk

> Included with your Eggdrop is an Eggdrop utility called ‘autobotchk’. Using autobotchk is probably the fastest way of creating your botchk and crontabbing it with just a few required steps:

> > 1.:

> >     cp scripts/autobotchk ..;

> > 2.:

> >     ./autobotchk <Eggdrop config file>

> This will hopefully crontab your bot using the default setup. If you want a list of autobotchk options, type ‘./autobotchk’. An example with options would be:

>     ./autobotchk <Eggdrop config file> -noemail -5

> This would setup crontab to run the botchk every 5 minutes and also to not send you email saying that it restarted your bot.
