我尝试以下操作：
roroco@roroco ~/Dropbox/rbs/ro_cmds $ echo $DBUS_SESSION_BUS_ADDRESS
unix:abstract=/tmp/dbus-KtyPDgWNin,guid=ca3ea893cf45d42ef60e74d0545d84f6
但是当我想列出这个套接字文件时，我似乎找不到它：
roroco@roroco ~/Dropbox/rbs/ro_cmds $ lsa /tmp/dbus-KtyPDgWNin
ls: cannot access /tmp/dbus-KtyPDgWNin: No such file or directory
