為什麼 gcsfuse 掛載後不返回命令提示符？

我已經成功安裝了gcsfuse。當我執行它時，它會列印出來，File system has been successfully mounted但我不會回到 shell 提示符。（見下面的成績單。）我做錯了什麼？

確認儲存桶存在：

ybaruy_gmail_com@test-fuse:~$ gsutil ls

Updates are available for some Cloud SDK components.  To install

執行 gcsfuse：

ybaruy_gmail_com@test-fuse:~$ gcsfuse yossi-fuse-bucket mount-point
2015/08/04 05:51:44.524655 Warning: low file rlimit of 1024 will cause cached content to be frequently evicted. Consider raising with `ulimit -n`.
2015/08/04 05:51:44.954706 File system has been successfully mounted.

預計該gcsfuse命令不會返回到 shell — 它在前台執行，直到文件系統被解除安裝（使用fusermount -u）或它接收SIGINT到，通常通過按 Ctrl-C。有關更多詳細資訊，請參閱文件。

如果您想在文件系統在前台執行時與它進行互動，您需要打開另一個 SSH 會話並在那裡進行。或者，您可以使用幫助程序，例如daemon將 gcsfuse 變成在後台執行的守護程序，甚至在您的fstab. 有關詳細資訊，請參閱文件中名為“作為守護程序執行”的部分。
