Full path folder on linux console

When you log on to linux console, usually you see something like

web@w22 log $

comp-web : user who log in;  w22  : host name ; log : current folder.

But you dont know full folder path, to show that use this command

$ export PS1="\[33[01;32m\]\u@\h \[33[01;34m\]\w \$ \[33[00m\]"
