How to feed command line argument to git-bash.exe?

[diffuseinstability]

I'm running Stable Diffusion on Windows 11 with the Automatic1111 Web UI using the Git Bash (git-bash.exe) emulation layer (https://www.atlassian.com/git/tutorials/git-bash). Currently, I have to launch git-bash.exe using a shortcut I created in my Start Menu, copy and paste in a long command to change the current directory, then copy and paste another long command to run webui-user.bat. I can't even use hotkeys, because Ctrl+V doesn't work in Git Bash.

What I want to be able to do is create a shortcut or .bat file that feeds Git Bash a command line argument instructing it to run a (different) .bat file that, in turn, contains the commands to change the directory and run webui-user.bat. In other words, I want a a shortcut or .bat file will use the Windows OS to run Git Bash, but also feed Git Bash a command to run with the emulation environment.

Does anyone know how to feed such a command line argument to git-bash.exe?

Failing that, does anyone know where to any other method for setting a 1-click execution of this setup? Or even a list of commands that can be executed on the command line for git-bash.exe?

For arguments sake, let's assume

Git Bash executable: C:\Program Files\Git\git-bash.exe

Automatic1111 UI: C:\Users\thisuser\SD\webui-user.bat

Default directory used as Git Bash "home" upon start up: C:\Users\thisuser\

Do you need Git Bash at all? If all you want to run a .bat, then just run that .bat, using CMD. If you chose the option to add Git to the PATH (the default, which appends ;C:\Program Files\Git\cmd to the environment variable PATH), that Batch file should have access to git.exe and it should not need to involve Bash at all.

I'm not trying to run Git. I'm trying to run Stable Diffusion using Git Bash.

But why the need for Bash? If all you want is to run a Batch file?
