我如何确保一个进程正在运行，即使它自杀了?(需要重新启动)

I'm using linux. I want a process (an irc bot) to run every time I start the computer. But I've got a problem: The network is bad and it disconnects often, so I need to manually restart the bot a few times a day. How do I automate that?I'm using linux. I want a process (an irc bot)
