Linux mint's bash.bashrc

You can refer to the following statement :
vim /etc/bash.bashrc

PS1='\[\033[1;33m\]\u\[\033[1;37m\]@\[\033[1;32m\]\h\[\033[1;37m\]:\[\033[1;31m\]\w \[\033[1;36m\]-> \[\033[0m\]'

Note :
\u    User right now .
\w   show  full path .
\W  show folder name right now .
@ or #   you can change to your favorite symbol .
