Bash PS1 shows $ instead of # for root

Question

When you enter the root folder, the default prompt for the echo \s-\v\$is displayed as bash-4.2#. I'm trying to play around with a bash prompt so that it displays the working directory. export PS1="\w \$".

It is displayed correctly on the right, however, the character is \$not converted to #, although mine $UIDis 0, which leads to the victory in skipping the user's character \u. Is there anything extra that I have to add, or does this symbol not work if I export it?

Answer 1

export PS1="\w \$"

$PS1 \w \$, \w $, , :

echo "$PS1"

:

export PS1='\w \$'

Answer 2

export PS1="\w \\$"

Answer 3

the trait will disappear in "". Just need to add another one to save it. Or

export PS1='\w \$'

or

export PS1="\w \\$"

works for you.

You can combine "and". For instance:

export PS1="\w blabla"'\$'
