postgresql

I am running a GUI app (Gnucash) that connects to a remote Postgres database via a secure shell session. I can use the SSH -L command to tunnel a local port and then separately run Gnucash and this works fine.

What I'd like to do is use a single shell script that sets up the tunnel and then calls Gnucash. Is that possible? If so, how do I do it? Currently, I run commands like the following in 2 separate terminal windows:

ssh -L 5433:127.0.0.1:19097 [email protected] gnucash postgres://gnucash@localhost:5433/gnucash_db

If I simply put both lines in a shell script, the first line drops me into the remote shell and the second line doesn't execute until I exit the remote shell.

TIA, Rob Hills
