Currently I use Fish as my main shell on local and remote hosts.
I connect to remote hosts via ssh and sftp. I wanted to open or reuse a remote tmux whenever I connect, automatically, by default; so I added this to my
Host example.com RemoteCommand tmux a; or tmux RequestTTY yes
The problem is that now I cannot connect through
sftp, nor can I run a direct command from my local CLI:
➤ ssh example.com ping localhost Cannot execute command-line and remote command. ➤ sftp example.com Cannot execute command-line and remote command. Connection closed
So, my question is: How can I define a default command to be executed when opening a new interactive SSH session, but make it overridable?
