How to automatically change a buffer terminal name?

Question

I have a small .bat file to open Vim along with a terminal running an IPython console:

@echo off
call C:\Users\myname\Miniconda3\condabin\activate.bat C:\Users\myname\Miniconda3\envs\myenv
gvim -c "vert botright terminal C:\Users\myname\Miniconda3\condabin\conda.bat activate myenv  &&echo Conda env:%CONDA_DEFAULT_ENV%  &&ipython"

I am fairly happy, but the name of the terminal buffer is fairly annoying:

C:\Users\myname\Miniconda3\condabin\conda.bat activate myenv...

Hence, I manually change the name of such a terminal by putting the focus on the terminal buffer and by issuing <c-W>:file IPYTHON but this is very boring and error prone.

A solution would be to automatically run the command :file IPYTHON after I launched :terminal but from the documentation that does not seems to be possible.

How can I solve my problem then? Shall I modify my .vimrc file? If so, how?

Instead of executing the command :terminal, we can use the function term_start which provides us with several optional options, one of which lets us set the buffer name.

From :h term_start:

term_start({cmd} [, {options}])         *term_start()*
        Open a terminal window and run {cmd} in it.
        <snip>         
        There are extra options:
           "term_name"       name to use for the buffer name, instead
                     of the command name.
           <snip>

Using the above, we can refactor OP's batch script accordingly:

@echo off
call C:\Users\myname\Miniconda3\condabin\activate.bat C:\Users\myname\Miniconda3\envs\myenv
gvim -c "vert botright call term_start('C:\\Users\\myname\\Miniconda3\\condabin\\conda.bat activate myenv && echo Conda env:%CONDA_DEFAULT_ENV% && ipython', {'term_name': 'IPython'})"
