This video shows how to create and resize claims using the shovel. Depending on circumstances, you might find this an easier way to manage claims than using commands:
Listing and Deleting claims
/listclaims - Lists all your claims and the amount of claim blocks available to you.
/abandonclaim - Abandons the claim you're standing in.
/abandonallclaims - Abandons all claims you own.
Giving claim trust to other players
/trust player - gives player permission to build, destroy, etc, and everything in /accesstrust and /containertrust
/accesstrust player - gives player permission to use doors, levers, buttons, fence gates, etc.
/containertrust player - gives player permission to open chests and other containers, and perform farming tasks, such as milking cows, killing and breeding animals, destroying and planting crops, etc, and everything in /accesstrust
/permissiontrust player - gives player permission to /trust and /untrust other players.
Note: You can use public in place of player to give that trust to all players. Generally useful for /accesstrust to allow others to open doors and push buttons, but preventing them from killing animals or breaking blocks.
Managing the claim trust list
/trustlist - Lists players you've trusted to the claim you're standing in.
/untrust player - Removes player from your trust list inside the claim. To remove the player from all of your claims, stand outside the claim when executing the command.
/untrust all - Removes everyone from your trust list for that claim.
