Understanding weird character syntax in PS1 bash prompt

Question

Here is my bash prompt:

Here is the PS1 that generates that

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]`__git_ps1`    \$ '

Now, here is the stuff I understand:

• $debian_chroot - used for su & sudo
• u - user
• h - host
• rest chars like \033 are for colors.

What I don't understand is what is generating space AFTER rails and BEFORE (master)? What character does that? I would like to remove that space.

Answer 1

The __git_ps1 function is generating it. Edit the file the function is defined in.
