remote ssh command issue

Question

Team,

I am facing some difficulties running commands on a remote machine. I am unable to understand why ssh is trying to think that the command I pass is a host.

ssh -tt -i /root/.ssh/teamuser.pem teamuser@myserver 'cd ~/bin && ./ssh-out.sh'

ssh: Could not resolve hostname cd: No address associated with hostname
Connection to myserver closed.

It works absolutely fine if I don't pass a command. It simply logs me in. Any ideas?

Man ssh says:

If command is specified, it is executed on the remote host instead of a login shell.

The thing is that cd is a bash built-in (run type cd in your terminal). So, ssh tries to run cd as a shell, but can not find it in PATH .

You should invoke ssh something like this:

 ssh user@host  -t 'bash -l -c "cd ~/bin && ./ssh-out.sh"'
