Fink installation: After installation (I believe): -bash: fink: command not found

I want to install "fink"to my new MacBookpro, when The core packages have been updated. You should now update the other packages using commands like 'fink update-all'. I assumed that fink has been successfully installed, but when I tried to follow the instruction call the command: fink update-all -bash: fink: command not found Is this expected? Or did I do something wrong? Any information is needed to do the trouble shooting, please let me know.
