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.

If you want your PATH updated only upon logging in, edit ~/.bash_profile (usually Red Hat/rpm-based systems) or ~/.profile for Debian-based systems (at least for Ubuntu).
Please note PATH is exported. PATH is usually defined/updated in the login-only files, rather than .bashrc, which is executed, I believe, every time a shell starts up.
It was not clear from your post if you were adding to PATH on the command line or in a login file as noted above. Unless you absolutely do not want a launched program to have your modified PATH, pre-prending export to the environment variable is a useful thing to do (with any environment variable for that matter).
Thanks, but that's what I did. In a bash terminal I put
PATH=$PATH:/usr/lib export PATH in one line, then pressed enter.
I also put exactly that in my home .bash_profile, and to be sure in /etc/profile. On restart, echo $PATH gave me the old PATH again, without /usr/lib That's why I thought I'm doing something wrong here! Am I?
/etc/profile is a root file, ie only root can modify it. But I started gedit as su to add /usr/lib and the others. But on starting the computer this morning I still only have $PATH=/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games
Oh, and /etc/profile was there, I just modified it, according to what I read on the net. Wouldn't know how to write a script!
Far as I can see, I'm not doing anything wrong, but it doesn't work!!! Maybe missed a dot or a comma???
