rsync 無法使用 -o StrictHostKeyChecking=no 選項

下面的 rsync 工作並幫助將遠端目錄複製到本地主機

/bin/rsync -rv myremoteuser@myremotehost:/tmp/Deployments/ /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/

一旦我添加-o StrictHostKeyChecking=no它失敗並出現以下錯誤：

/bin/rsync -rv -o StrictHostKeyChecking=no myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/
Unexpected remote arg: myremoteuser@myremotehost:/tmp/Deployments
rsync error: syntax or usage error (code 1) at main.c(1348) [sender=3.1.2]

我希望它能夠工作並且當我將它放在雙引號下時也能工作，如下所示：

"/bin/rsync -rv -o StrictHostKeyChecking=no myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/"
bash: /bin/rsync -rv -o StrictHostKeyChecking=no myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/: No such file or directory

以下是詳細資訊：

-oRsync在其命令行上不採用 ssh選項。您必須將 ssh 選項放入傳遞給 rsync-e選項的 ssh 命令字元串中。就像是：

/bin/rsync -rv -e 'ssh -o StrictHostKeyChecking=no' myremoteuser@myremotehost:/tmp/Deployments /web/playbooks/automation/getfiles/tmpfiles/4/E5EA787E/myremotehost/

正如您所提到的，您應該能夠將上述內容用雙引號括起來，因為-e參數是單引號。手冊頁還提到使用RSYNC_RSH環境變數作為-e命令行選項的替代方案。
