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
party - set OS responses mode SYNOPSIS
party ON|OFF|WHEREIS [ - ] dnv DESCRIPTION
Operating systems being what they are, the admin people can easily grow tired of command responses that resemble dyslexic eugene- speak filtered through Kernighan and Ritchie's collective back-brains. To alleviate this, we have included a slightly more `casual' mode, in which the responses to all commands are first filtered through a customising routine (DUDE) , which makes them sound a little more friendly while retaining their full information content (usually). The rooted(c) system prompt is changed to `What now, dude?' and output from each command is terminated by `No problem, dude.' OPTIONS
-v Verbose mode (ALL commands have a `verbose' mode). When this option is present, all filtered responses are preceeded by a message: `This response has been parsed by the DUDE filter and is not intended to be some sort of sleazy come-on.' -d Don't restart all processes after recompiling the /uselss/libs/eugene file (see below). This alows any important tasks to complete beforehand. -n Notify all users that they are about to be force-logged out and force-logged in again. ON Activates the DUDE filter. OFF De-activates the DUDE filter. WHEREIS Doesn't do anything, but we couldn't resist it. EXAMPLES
%-) party on What now, dude? To compare the differing responses, here is output provided by the ispi -s command, with party OFF and party ON: party OFF line who why how long ========================================================== 000 rooted that's you, dweeb! epoch ---------------------------------------------------------- 00F wp she's supposed to be 0:44:12 typing up the end of financial year report, but she's been doing her resume when she thinks no-one is watching ---------------------------------------------------------- 014 maint playing games, as usual 0:51:16 party ON Well, let's see who's on, eh? There's you, of course, on line 000 (Imagine that! Hahaha!) Oh look, on serIOus line 00F, it's that cute little secretary - looks like she's lost her keyboard template again, she's been hitting the escape key for the past five minutes! AND OF COURSE, the guys down in maintenance are playing `cosmic ballcrushers'. As usual. Well, who else, um, no-one really interesting like, ya know, oh hang on, DTR is toggling on serIOus line 03D.. oh, no problem, it's that stuffed modem again. You want maybe I should send some AMail to maintenance and get 'em to look at it? No problem, dude. What now, dude? FILES
/uselss/libs/bill&ted/DUDE This is the pipe process, usually started at system shoe, which lies idle until party ON is issued. /uselss/libs/eugene Contains all of the ordinary, ho-hum confusing computer - jargonese responses which commands ordinarily issue. Text file. /uselss/libs/eugene.spoo compiled version of the eugene file. /ephemeral/eugene.chex Checksum for the compiled eugene file. SEE ALSO
crp(1), stuffio(2), doobrie(9), gouge(3), ftang(65534), wi(-1), edmond(29), jumpstart(2), vo_mit(992) BUGS
The -n option can be slow. If the n option is issued, some users in a wi editing session may not receive the `warning, restart imminent' message until after the restart. There is no way selectively to follow symbolic links. Sunburne Computer, Inc. 9 October 1991 Aug 18, 1997 PARTY(1)
