Is it possible that a script knows where it was called?

Question

I have a script.sh and I wonder if there’s any way he could know where he was called.

ex:

comando=$(existe algum comando pra isso?)
variavel=$AlgumaVariavelDeAmbienteTalvez

if [[ $comando == "x" ]]; then
  echo "fui chamado pelo prompt do windows"

elseif [[ $variavel == "y" ]]; then
  echo "fui chamado pelo terminal do git bash"

elseif [[ $variavel == "z" ]]; then
  echo "fui chamado pelo ctrl + r (executar do windows)"

elseif [[ $comando == "teste" ]]; then
  echo "fui clicado!!<---"
fi

As in the example, there is some variable or command that allows me to identify how it was called??
