Run a remote command using ssh config file

Question

I'd like to be able to setup a command to run on ssh login to a server, without needing to type it. Basically I'm looking for the ssh config file equivalent of:

ssh host command

so that all I need to type is:

ssh host

and the command gets run.

Answer 1

You could set up a bash alias.

In your .bashrc file, put:

alias ssl='ssh some_host run_command'

Then you wouldn't even have to type the hostname.

Or, if you wanted to do this with multiple hosts(and multiple aliases wouldn't work), then use a small script:

kevin@box:~$ cat ssl.sh
#!/bin/sh
ssh $1 some_command
kevin@box:~$

Answer 2

If you are running OpenSSH, it looks like ~/.ssh/rc is executed upon login.
