How to get access to Google Drive from terminal
Arguments to commands in Bash (the language used in Terminal) are separated by spaces. So when you write cd Google Drive, you're passing two arguments to cd - Google and Drive. cd is just ignoring the second argument and trying to cd into the directory called Google, which doesn't exist.
In order to cd into Google Drive, you need to write cd Google\ Drive or cd "Google Drive". The \ escapes the space character and treats it as a single string.
I would also type cd Goo and then press tabso it would autocomplete with the escaped space character.
As Google Drive has a space in between the words you need to quote the directory name.
Try cd 'Google Drive'
