I know this question has been asked a million times, but my ~/.gitconfig consists of only two lines, that are character correct with the tutorial.
git config
This is my ~/.gitconfig:
[user]
name = Luigi R. Viggiano
email = luigi.viggiano@...
[color]
ui = true
[merge]
tool = p4merge
[diff]
tool = p4merge
[push]
default = simple
your ~/.gitconfig is not in the correct format.
You don't need to put the commands:
git config --global user.name "trx"
git config --global user.email chazx@live.com
in a file... you need to type them at the terminal.
Delete your ~/.gitconfig and manipulate it using the git config command at the terminal, as explained in the tutorial.
