我有 aws 实例密钥 .pem 文件，我将其保存在文件夹中
"home/debian/cs605\ data\ management/assignment6/mumbai\ instance\ keys"
键名是 mumbai-instance-1.pem
我写了一个像这样的小 bash 脚本
!/bin/bash
AWS_KEY="home/debian/cs605\ data\ management/assignment6/mumbai\ instance\ keys"
ssh -v -i $AWS_KEY/mumbai-instance-1.pem
[email protected]
上面的文件保存在以下文件夹中，名为 mumbai
/home/debian/cs605 数据管理/assignment6
现在我尝试在之后启动脚本，chmox +x mumbai
但出现错误
Warning: Identity file home/debian/cs605\ not accessible: No such file or directory.
OpenSSH_8.0p1 Ubuntu-6build1, OpenSSL 1.1.1c 28 May 2019

ssh: Could not resolve hostname data\\: Name or service not known
./mumbai: line 6: [email protected]: command not found
那么这个错误是什么，我该如何摆脱这个错误。
更新1
我尝试了答案中提到的方法
debian@osboxes:~/cs605 data management/assignment6$ ./mumbai

我检查了文件的权限
debian@osboxes:~/cs605 data management/assignment6/mumbai instance keys$ ls -l
total 8
-rwxr-xr-x 1 debian debian 1692 Mar 3 14:24 mumbai-instance-1.pem
-rwxrw-rw- 1 debian debian 1464 Mar 3 14:30 mumbai-instance-pvt.ppk
所以我认为这不应该是权限问题。
我在上面的 AWS_KEY 中犯了一个错误，应该是 /home
更新2
现在，在解决上述问题时，当我使用 AWS_KEY="/home/debian/cs605\ data\ management/assignment6/mumbai\ instance\ keys" 执行上述脚本时，我得到了关注

好的，我修复了它，密钥文件应该有 700 权限，750 或 755 是不可接受的。
这是因为路径中有空格，在这种情况下，您必须使用引号。
试试这个方法：
只需删除变量中多余的斜杠
$AWS_KEY并在使用""时使用。
