Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I reveal you a secret: there is no executable called tcl. The /usr/lib/tcl and /usr/share/tcl reported by the whereis command are indeed two directories. If you want to interactively run tcl commands, you have to type:
The >> symbol, as maybe you already know, means "append to". The output of the echo command has been appended as a new line at the end of the file ~/.bashrc. At this point you have to edit this file and delete the unwanted line. In Opensuse you can use kwrite. To launch it from a terminal, just issue:
yes, i know that . I had allready tried in VI editor. but i haven't found line related to that command. Please once look at my .bashrc file
# Sample .bashrc for SuSE Linux
# Copyright (c) SuSE GmbH Nuernberg
# There are 3 different types of shells in bash: the login shell, normal shell
# and interactive shell. Login shells read ~/.profile and interactive shells
# read ~/.bashrc; in our setup, /etc/profile sources ~/.bashrc - thus all
# settings made here will also take effect in a login shell.
# NOTE: It is recommended to make language settings in ~/.profile rather than
# here, since multilingual X sessions would not work properly if LANG is over-
# ridden in every subshell.
# Some applications read the EDITOR variable to determine your favourite text
# editor. So uncomment the line below and enter the editor of your choice :-)
# For some news readers it makes sense to specify the NEWSSERVER variable here
# If you want to use a Palm device with Linux, uncomment the two lines below.
# For some (older) Palm Pilots, you might need to set a lower baud rate
# e.g. 57600 or 38400; lowest is 9600 (very slow!)
Well, the command is quite clear and the line should have been added to .bashrc. Maybe you were logged as root when applying that command? Check the files ~/.bashrc of root and of the users you normally use on this machine.
Thank you very much for replying me !!
i had edited those 2 lines .
I had deleted the statements after : at the end of each of two lines
and " /usr/lib/tcl/"
Now i am not getting any error message after opening of terminal in "su" mode .
