isnt cd -
supposed to go back to the previous line??

Not that I'm aware of ... by "last line" you mean the last command that was entered? If you mean the previous directory, then it's cd ..

another question, im looking at this book that has these exercises but let me show u what happens

(swindon)34% cd ~/IN2011
(swindon)35% cd
(swindon)36% pwd
/u3.bath/s19/cv896
(swindon)37% pwd
/u3.bath/s19/cv896
(swindon)38%

after typing cd ~/IN2011 it asked to type cd followed by pwd and something is supposed to change

but i dont get whats happening in the replies

The tilde changes to your home directory, so the first command changes to the IN2011 directory inside your home directory.

The cd command by itself switches to your home directory since you're not supplying it with any parameters.

And pwd just displays the current directory you're in, which appears to be /u3.bath/s19/cv896 (your home directory)

What else does your book say? What's supposed to change?

NAME

       cd - Change working directory

SYNOPSIS

       cd ?dirName?
_________________________________________________________________

DESCRIPTION

       Change the current working directory to dirName, or to the home directory (as specified in the HOME environment variable) if dirName is not
       given.  Returns an empty string.  Note that the current working directory is a per-process resource; the cd  command  changes  the  working
       directory for all interpreters and (in a threaded environment) all threads.

EXAMPLES

       Change to the home directory of the user fred:
	      cd ~fred

       Change to the directory lib that is a sibling directory of the current one:
	      cd ../lib
