They are numbers all right - but if you connect to that port, you should,
normally, find something listening there (if there's a daemon running which
listens at that port, at least).  port 25 = smtp, so you'll see sendmail or
whatever running.  port 110 = pop server, and so on.

the PATH variable can be set in /etc/profile or /etc/bashrc ...
