This command does not work in windows and gives an error message "Couldn't find program: 'bash'" (Screen shot attached)

Kindly resolve it

Hi @popa112, Bash is not available on Windows, it's present on Unix platforms. You can download the Git Bash tool to add a version of Bash with some limited features which should help, or you can use the Windows Subsystem for Linux (WSL2). Otherwise, if you have a fairly recent version of Windows, you can likely use

!powershell -Command "pybamm_edit_parameter <...>"

in place of %%bash

Note that the pybamm_edit_parameter commands were deprecated in 22.10 (#2342). Parameters now can be defined directly in scripts using the ParameterValues class.

Thanks. Can you write a command for it so that I could create a copy ?

From where I can get Git Bash Tool?

You may get the Git Bash tool via Git for Windows (https://gitforwindows.org/). For the new way to define parameters, you may scroll through the documentation at https://docs.pybamm.org/en/stable/source/api/parameters/parameter_values.html and these notebooks:

1. https://docs.pybamm.org/en/stable/source/examples/notebooks/getting_started/tutorial-4-setting-parameter-values.html
2. https://docs.pybamm.org/en/stable/source/examples/notebooks/parameterization/parameter-values.html
