How to add path of a program to $PATH environment variable? [duplicate]

How to add a directory to my path?

I need to use a program in my job. I followed the installation instructions of this PROGRAM. However, when I try to run it the message appears - program_that_I_want_to_run:Command not found

I know that it is a $PATH problem, but I tried the command line described in the instructions and it did not work.

3. Set environment variable CONFIG_PATH

   export CONFIG_PATH=/my_path_to_PROGRAM/PROGRAM/config/

I am sure that I indicated correctly the path to access the config directory. No typing errors.

Help?

Firstly, check your original path:

echo $PATH

It should show something like this:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

Now add your program to that path, ensuring your using the entire path all the way from / to your program.

export PATH=$PATH:/path/to/my/program

This sets your PATH variable to the existing PATH plus what you add to the end. Check that it has been added (Caveat: it presist only in the current session of the terminal):

echo $PATH

Add this line to ~/.bashrc (you use PATH rather then CONFIG_PATH)

export PATH=$PATH:/path/to_directory_containing_program
export CONFIG_PATH=/my_path_to_PROGRAM/PROGRAM/config/
