Robs answer may be better for your specific situation, but to answer your original question:
- "echo %ssh" will echo the pids of all child jobs whose command line starts with 'ssh' - "echo %1" will echo the pid of job 1 (check 'job control' if you need to). - A command like 'fish -c "echo %self; exec ssh user@somewhere"' will start a new shell that will echo it's own pid and then exec ssh (keeping the pid). - I don't think there is an exact analogue to bash's $! that will expand into the pid of the last background process, but I can't think of any situation that can't be solved with one of the above solutions.
