bash path problem

[Sapna Mishra]

Hi all, 

Can any one tell me how to add a path in .bashrc file of a directory say Idl which contains so many sub directories such that when I do source .bashrc it is able to run all the codes and scripts inside all the different sub directories there??? 
Is it possible? I am doing 

IDL_PATH=.:+/idl/idl70/lib:/home/cs/Idl .... The Idl folder is having many sub-directories (eg. xidl, idl_code, net etc..) however I am only to run files in folder Idl but not of sub folders. 

Is there any way?

try this

IDL_PATH=`find /home/cs/Idl -type d | tr '\n' ':'`
