For the following please consider that I'm new to the Linux file system and have little understanding here.
When I log onto my cluster I do so on a default machine. The admin have setup several python distributions in the root and I've set the one that I want to use in my .bashrc. In my case and for illustration this distribution is:
export PATH="/csoft/epd-7.3.2/bin:$PATH";
I've been asked to execute scripts from another machine that I have to ssh to via the terminal. When I ssh to this machine that file system appears exactly the same (including the .bashrc). However, a different version of python is executed by default. How do I set the path for this ssh machine, those unique name can be determined via hostname?

"the path" meaning: "how do I execute a specific version of python"?

export PATH="/csoft/epd-7.3.2/bin:$PATH"; in the .bashrc. This is the path to the python that I need. The sys admins have several other python distributions that you can choose by setting this path appropriately.

so you need that particular $PATH set on a particular machine? Doeshostnameoruname -nreturn a unique value on that "other" machine that will uniquely identify it?

Yes it does have a unique name.

In your .bash_profile, include this (replacing unique-hostname-here with the output from uname -n on that host):
case $(uname -n) in
(unique-hostname-here) PATH="/csoft/epd-7.3.2/bin:$PATH"
;;
esac
This presumes that the PATH variable has already been populated and exported previously (or subsequently); no need to re-export it every time it's set.
Further reading on shell initialization files:
