Guys maybe this isn’t so related but I would appreciate if I get any help when I fist open the bash terminal what you get is a message prompt showing the machine name and mingw64, the one that is on my bash terminal is ‘ARAOLUWA@DESKTOP-ER6KM4N MINGW64 /’ if I run ls -a from this directory I do not see the c directory listed but if I run cd c the terminal takes me to the directory. I do not understand how this work, but I notice just running cd changes the massage promp to ‘ARAOLUWA@DESKTOP-ER6KM4N MINGW64 ~’ and changes my working directory to ‘c/user/araoluwa’ can somebody please explain to me why this is so… please?
