Normally, if you pass a command to ssh like so
ssh email@example.com 'some-command.sh'
You get a non-interactive session, and ssh exits as soon as the command (or script, or whatever) is run. How can I get an interactive session, and yet run a command that I've specified from my local machine. For instance, I'd like to be able to open screen and restart a specific screen session:
ssh firstname.lastname@example.org 'screen -r 12345'
but this is not allowed, returning the error "Must be connected to a terminal." which I presume means essentially "must call this command from an interactive shell".
As another example, I use a ton of machines at work that often require me to use a shared account to have rights to do certain things (yeah I know: bad idea but don't blame me, I didn't set things up that way), and they usually have ksh as the default shell. I'd like to log in, switch to bash (or zsh), and source my own account's .bash_profile (or .zshrc). This would be easy if I could establish an interactive ssh session and pass a command to the remote machine to run upon login.
I have a very kludgey (and untested) solution in mind that I will post, but I'm hoping someone knows a better way.
UPDATE: for those who didn't realize this, I'm not planning to do all this by hand, so telling me to open an interactive session and then do it by hand doesn't actually solve anything.
2nd UPDATE: To attempt once again to clarify: I'm trying to run (arbitrary) commands on the server (programmatically specified on the client) but then have an interactive session open that is affected by anything done by those programmatic commands.
