How to fix Mac terminal username format (missing colon and no spacing after the $)?

问题

I get a wrong username format when I launch my terminal. As a newbie, I could notice three errors: 1. a closed bracket ] appears instead of a colon 2. the $ sign is not followed by a single space 3. the first letter or character typed doesn't appear, for e.g. if I type ls, only the s would appear

Username: mymac, Computer name: MyMac’s MacBook Air

The extra ] can be disabled by :

1. opening the terminal
2. selecting edit menu bar
3. hovering over marks
4. unchecking automatically mark prompt lines

The default can be overridden by executing the following command:

echo 'export PS1="\\u@\h \W $ "' >> ~/.bash_profile
