Answer 1

You add the path to the executable to the PATH environment variable. For example, assuming a bash shell, and the path to the program /home/username/program/hello, you do the following:

export PATH=$PATH:/home/username/program

If you want this to be set automatically, add that line to ~/.bash_profile
