Default console in ConEmu

I have git bash setup as a predefined task (task #1). But when I open ConEmu it defaults to cmd console, how do I change the default console to git bash?

In the settings (Win + Alt + P), select 'Startup'. This allows you to select a single task using the third option, 'Specify named task'. You can use the other options to specify multiple tabs to open on startup.

How to launch from command line \ shortcut \ script

You can also make a shortcut using the /cmd command line switch:

"C:\Program Files\ConEmu\ConEmu64.exe" /cmd PowerShell

Replace PowerShell with whatever you named your task. Here is a document listing all of the command line options. Note that if you run this while ConEmu is already running it will just open a new tab in the current window. This is usually the desired behavior but this behavior can be overridden using the -new_console and -cur_console switches (depending on your current setup).

If you are using Windows 7 or higher, you may also be interested in looking at using the jump list to select a task to startup. This can be done in the 'Main' -> 'Task bar' options page. Check the 'Add ConEmu tasks to Task bar' box and press 'Update Now!'.
