I wouldn't call myself exactly new to Unix. I've played with Linux before so I can get around alright. I just have never really learned the basics, like setting a user's path. How do I do that on my Sun station? Obvioulsly, I've got several different bins, but I can only use the commands in /usr/bin because that's what my path is. How do I use the others?

According to which shell you are using you should find the variable PATH somewhere in one of these files in your home directory. Add whatever other paths you want to search to that variable.

/home/user/.profile
/home/user/.cshrc
/home/user/.login

Or you can add it to the default for ALL users - look in /etc
for

/etc/profile
/etc/default/login
