gpg>
2, using the list you can see the current user's key and user ID (or user name, comments):
gpg> list

Here can be divided into two cases,
1), has not been uploaded to the key server key to delete the key.
2), has been uploaded to the key server for a key, the original key if we are not then used, then the write-off logo on the use command to log off.
