1. The problem statement, all variables and given/known data:

I have been reading for several hours. Im not getting anywhere... well Im not getting there fast enough. so I thought I would ask the experts

I need to list and count directorys in root. this is part of a class im taking. I dont know scripting much at all. well not at all. still I need the out put to look like this

the root directory on "hostname" has "some number" directorys
#then list the directroys like this, or close to it.

2048 r-x 2 14:26 bin
512 r-x 2 15:59 bsd-src
3072 r-x 3 14:45 dev

and so on.

with ls -gko / I get some of what I need. but I need some hints/help with the rest.

ls -gko /

drxwr-xr-x 3 4 feb 2 2010 bin
drxwr-xr-x 3 4 feb 2 2010 boot

and for some reason, adding the -d option that I think should be giving me only directorys is giving me this one line.

drxwr-xr-x 33 4 Jan 3 13:46 /

help wanted

thanks



2. Relevant commands, code, scripts, algorithms:

I have been trying to use ls - options just to get the fields right but I understnad I will need to use
ls
echo
cd
and regular expressions.

3. The attempts at a solution (include all code and scripts):

Im posting this from windows and I cant get all the attemps from my linux machine to here. I can if I really have to but I think you can see I have been working on this problem for about 2 days now. Im just not good at c yet and this seem like a rather advanced problem for a intro to unix course.


4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

school = pima.edu
intro to unix =CSI137
instructor is B. Tucker


Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

Something like:

Code:

ls -gko / | egrep '^d'

?
And number of directories:

Code:

ls -gko / | egrep '^d' | wc -l

what is wc?

thanks for the help

ok.. I think I know what wc is supposed to do. but the output is a unexpected result

infact wc -l in the root dir just gives me a blank next line that I have to cntl c out of .

Did you run it the way I provided? With ls and egrep?

sorry.. I tryed to run it by its self..


so.. how do I hook long regular expressions together? or is that possible.

I thought I was to use ! but it seems there is some other operator that lets you string commande together? or do I need to assign varibles? this is really hard. I know nothing about programming
