# heidisql-ssh-tunnel

Helper script to spawn SSH tunnels based on HeidiSQL settings

# What's this?

The script assumes you have HeidiSQL directory in `~/'.heidisql` where your `portable_settings.txt` file is living.

It peeks into that file and offers auto-completion based on saved sessions. It creates local SSH tunnels for these sessions.

# Setup

1. Git clone this repo
1. Add a symlink to bash completion script such as:
    ```
    sudo ln -s <repo>/hs ~/.local/share/bash-completion/hs
    ```
1. Add symlink to script itself and make it executable:
    ```
    sudo ln -s <repo>/hs.sh /usr/local/bin/hs
    chmod +x <repo>/hs.sh
    ```

# What it looks like

Here with `fzf` as auto-completion helper (optional, is a personal preference):

> Here `hs` first attempts to set up an SSH tunnel for a HeidiSQL saved session and fails because something's already listening on the local port.
> 
> We `kill` the connection in question - an SSH tunnel from a prior test - and try again. This time `hs` correctly creates our tunnel. With `set -xv` we see the actual command that gets executed.
>
> Once done we clean up after ourselves and kill SSH tunnels we no longer need.
