That should work, but you'll have to tell the shell to re-read the file. try this: source ~/.bashrc technically you should put this stuff in ~/.bash_profile, log out and log in again. Otherwise you rick repeatedly redefining PATH and adding the same directory to it over and over again. Which is relatively harmless but can be annoying. you should also export the PATH variable so that it is passed to subshells (many shell commands run in a subshell) the 'correct' command in your bash startup files would be export PATH=$PATH:/home/compy/pythons the new dir should really go on the end of the path in case you inadvertently create a script with the same name as a system command. > No, you have to set the environment variable from within the path, > not modifying .bashrc. $PATH refers to your current path. no, it doesn't. I think you misunderstand. $PATH is the search path used by the shell when looking for executable commands. it is not your current working directory.
