SSH then change Shell
SSH usually executes the command you pass it as an argument and then disconnects. You'll need three options set to get your interactive session to work:
ssh -twill force the pseudo-tty allocation necessary for you to interact with the remote command you're asking SSH to runbash -lwill start an interactive login shellcsh -l -cwill start an interactive login shell in csh, and then execute the command that follows
To just launch a different shell (i.e., your default is csh, and you want to launch bash):
ssh -t <user>@<server> "bash -l"To pickup the csh environment first, we start the interactive shell, and then pass the command to switch to bash:
ssh -t <user>@<server> 'csh -l -c "bash"'
