For a list of wikibots, see [1].

A bot is a computer program which plays NetHack without human intervention. Several bots now exist, and some of these can survive for a significant amount of time. A true bot with an internal model of the game, capable of making reasoned decisions about game events, and ultimately capable of ascending remained elusive until 2015-01-25, when smartbot3, based on BotHack first ascended on (see dumplog, ttyrec and other data).

The concept of a bot is often brought up in RGRN. Most conversations conclude that a bot is in theory possible, but tremendously difficult.

There exists a simple Perl script which is used by pudding farmers to automate the process of offering, praying, and clearing messages.

It is also possible to copy and paste a list of commands into a NetHack window which will repeat the same process over and over again. This was first used by eit_brad to achieve a high score which overflowed NetHack's signed 32-bit score variable in the 2003 /dev/null/nethack tournament.
