If your command is longer than 100 characters, it needs to be executed with a command block. Obtain one by typing:
/give @p command_block
You can give the armor stand a custom player head! Just replace Notch with an username of your choice.
/give @p skull 1 3 {SkullOwner:"Notch"}
You can use the following command to fully customise the equipment of your armorstand.
In order for it to work, you have to put a command block close to the armorstand you want to edit. (Notice the r=2, where the r is radius.)
/entitydata @e[r=2,ArmorStand] {Equipment:[{id:"iron_sword",Count:1b},{id:"iron_boots",Count:1b},{id:"iron_leggings",Count:1b},{id:"iron_chestplate",Count:1b},{id:"iron_helmet",Count:1b}]}
If you are a mapmaker you might not want players to take items out of the armor stand. If you want to lock all slots, replace n with 1 (or 0 if you want to unlock it).
If you want to
disable specific slots, you have to add the numbers in following table up, and replace n with your result.
| Boots | 2 |
| Leggings | 4 |
| Chestplate | 8 |
| Helmet/Block | 16 |
| Sword/Block | Not working :( |
/entitydata @e[r=2,ArmorStand] {DisabledSlots:n}
