bitcoin core command line walletpassphrase incorrect but works for the main system? My command line won't accept my passphrase, but on the main system it says it's correct and I can change it. I want to dump private key but no matter what I try, it continues to say incorrect passphrase. What can I do?
If your passphrase contains spaces or special characters, you will need to wrap it with single quotes (') so that the debug console can properly parse your passphrase. For example, if your passphrase were This is my passphrase, then your command should be 

walletpassphrase 'This is my passphrase'
