PS1 bash command substitution not working on windows 10

Question

This is my script that sets up my bash PS1

# Reset
Color_Off="\[\033[0m\]"       # Text Reset

# Regular Colors
Black="\[\033[0;30m\]"        # Black
Red="\[\033[0;31m\]"          # Red
Green="\[\033[0;32m\]"        # Green
Yellow="\[\033[0;33m\]"       # Yellow
Blue="\[\033[0;34m\]"         # Blue
Purple="\[\033[0;35m\]"       # Purple
Cyan="\[\033[0;36m\]"         # Cyan
White="\[\033[0;37m\]"        # White

# Bold
BBlack="\[\033[1;30m\]"       # Black
BRed="\[\033[1;31m\]"         # Red
BGreen="\[\033[1;32m\]"       # Green
BYellow="\[\033[1;33m\]"      # Yellow
BBlue="\[\033[1;34m\]"        # Blue
BPurple="\[\033[1;35m\]"      # Purple
BCyan="\[\033[1;36m\]"        # Cyan
BWhite="\[\033[1;37m\]"       # White

GIT_PS1_SHOWDIRTYSTATE="true"

PS1="\n${BBlack}\u@\h ${BRed}\w${BYellow}\$(__git_ps1 ' { %s }')${BGreen}\n$ "

It was working perfectly until yesterday when I decided to update my laptop to windows 10.

Now it throws this error:

bash: command substitution: line 1: syntax error near unexpected token `)'
bash: command substitution: line 1: `__git_ps1 ' { %s }')'

Any idea on what is causing this error?

Answer 1

The problem is the ending new line inside the ps1. I found the solution here . Changed my PS1 to:

PS1="\n${BBlack}\u@\h ${BRed}\w${BYellow}\$(__git_ps1 ' { %s }')${BGreen}"$'\n$ '

Answer 2

I think the error comes from here \\$(__git_ps1.....

It should be $(__git_ps1..... (without '\\')

I have tested this on (windows 10 / git 2.10.2):

PS1="\n${White}\u@\h ${BRed}\w${BYellow} $(__git_ps1 ' { %s }')${BGreen}\n$ ${Color_Off}"

and no problem
