This command should show all invisible file also.

ls-a

Create file .bash_profile if it doesn’t exist.

touch .bash_profile

Open file .bash_profile in text editor or editor of your choice.

open .bash_profile

Now append this code for .bash_profile file.

if [ -f ~/.git-completion.bash ]; then
    . ~/.git-completion.bash
fi

Save it and close the terminal.
