用命令改变当前用户的用户名

usermod 帮助中有这么一段:


CAVEATS
      [color="Red"] usermod will not allow you to change the name of a user who is logged
       in. You must make certain that the named user is not executing any
       processes when this command is being executed if the user’s numerical
       user ID is being changed. You must change the owner of any crontab
       files manually. You must change the owner of any at jobs manually. You
       must make any changes involving NIS on the NIS server.
