This tells your shell to execute the contents of the script.

This tells your shell to start a new shell, cd /mnt/w2k/download/Linux,
then exit, which returns you back to your previous shell which is still
in the kpu directory.  Add a pwd command before and after your cd to
illustrate what is happening.

That would be:
./linux

. is not in your PATH and for generally good reasons.

I think an alias would be more appropriate.  Also, look into the pushd
and popd commands.  They are infinitely more useful than cd.

alias linux="cd /mnt/w2k/download/Linux"
