bash – 使用ssh手动加载私钥

是否可以在忽略默认.ssh目录的情况下运行ssh并指定其他一个或 – 更好指定的私钥？

例如：

ssh --private-key other_id_rsa login@host

您可以使用-i选项.

来源：man ssh

-i identity_file
    Selects a file from which the identity (private key) for public key authentication is read.  The default is ~/.ssh/identity for protocol
    version 1,and ~/.ssh/id_dsa,~/.ssh/id_ecdsa and ~/.ssh/id_rsa for protocol version 2.  Identity files may also be specified on a per-
    host basis in the configuration file.  It is possible to have multiple -i options (and multiple identities specified in configuration
    files).  ssh will also try to load certificate information from the filename obtained by appending -cert.pub to identity filenames.
