If you usually use the gitbash console in Windows and you prefer to use it also in your Intellij you can change the terminal easily.
Open Intellij settings
First open the IntelliJ settings
Look for terminal options
In the terminal options change the default terminal to gitbash
Choose bash.exe in the path where you have Git installed inside the bin folder
Open the IntelliJ terminal again
Close the terminal and reopen it.
That’s all. You already have a gitbash terminal in your IntelliJ
