Question SSH: running various commands on a router


I have set up ssh to connect with a RSA key to a router. Now, I want to be able to run a chain of commands on that router the problem is that I can't send them separated with ; cause the router doesn't understand the separation, so I have to send the "<enter>" keys somehow.

I tried to do it like this:

( echo ping localhost; echo ping localhost; ) | ssh -i blah user@router

The connection is established, but it gets broken after login and no command is executed.

Is there a way I could tell ssh to read a text file where the chain of commands is?

Thanks in advance

What about trying the "\n" character sequence i.e.

ssh -i blah user@router "Command1\n Command2\n"

the \n trick, I would expect it to work, however the problem is a little more complicated, as the commands are in a text file. What I finally did was this:

ssh user@host "`cat file_with_commands`"

And it works.


commands, ssh
