I am new to Ubuntu (coming from Windows 7) and I am trying to add a directory to my system path and for some reason I can't get it to work. I am using Ubuntu version 12.04 LTS

I tried following this article without success How to add a directory to the PATH?

Here are my steps:

1. In my home directory I am editing the .profile file.



2. Under the “# set PATH so it includes user's private bin if it exists” section I added the following:

   
   
   

   if [ -d "$HOME/bin" ] ; then 
   
      PATH="$HOME/bin:$PATH:home/vincent/google_appengine"  
   
   fi
   
   




3. I logout and log back in.




4. open the terminal window and type in:

   
   
   

   vincent@ubuntu:~$ dev_appserver.py 
   
   dev_appserver.py: command not found
   
   

The directory and files are in the location. What am I doing wrong?
