Environment variables for bash
 

When I run the set command in the bash shell of my SUSE 10.1 Linux version, I get the usual list of environmental varialbes but at the end of the output there is a very large quantity of text that appears to be a shell script of some kind. What is it? Does it indicate a bug in my system? If I go into the plain old Bourne shell by typing
htarko@linux-betz:~> sh
only the environmental variables are printed and the extra output is gone.

The OS runs fine otherwise. I am enclosing a small fragment of the output. It is very long. Thanks for any help you can give.

Those are just some predefined convenience functions that you can use from the console. For example, spwd will return the last two directories of your current working directory:
