Vi games What games will help me learn vi? This may seem a bit silly, but there are many games on Unix systems that can help you learn to use vi. These help particularly with the basics. Although I don't know of any games that help with every vi command, I do know of a few that will help you learn to use hjkl to move the cursor around. NetHack, a rogue-like game, is particularly good for this, as it is a large game and can be entertaining for quite some time. Nethack is available from ftp.uu.net in /pub/games/nethack. Not to make the other games sound worse, but some other ones are rogue, moria, omega, worm, and snake. |
