My `conda_stuff` script, put in `$HOME/bin` and sourced with `. conda_stuff`:
```bash
# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
eval "$('/cygdrive/c/Users/john/anaconda3/Scripts/conda.exe' 'shell.bash' 'hook')"
# <<< conda initialize <<<


conda activate py39a # we're using this environment mainly
```
