oh ok, that makes sense. So how do set path for each program?
I have done the following:
PATH=$PATH:/usr/local/bin
export PATH
is that correct?
but do I have to do it for every program I install?
if I want one program to access the information in another program do I have to set the path for every program that it needs to access? and if so, how do I do that?
thank you very much for your help!!!!!!
