I would have /home/tom/bin at the end of the path, not at the beginning. 
Please show the output of the following command: 

grep PATH ~/.bashrc

I am surprised at how many instances of less you have. 
When you are tired of looking at the output of one 
instance of less, how do you get out of less to the 
command line?
