Homework & Coursework Questions

I think I'm working on Soralis, Minted/Wiked if either of these words mean anything to you, but the type of questions I'm working through right now with this basic method, or am I wrong in saying that?

Bump? I'm still in need of help with my latest questions, and pretty soon if its not too much trouble.

To check in on solaris:

Code:

 uname -sr

What have you managed so far?
e.g.

Code:

grep '.*:[10]:*:*:*$' carslist.txt

Explain to me what the above code is supposed to do.

I'm not sure I undrstand what you mean by 'what I've managed' sorry.

And yeah, in that code I am trying to find all the car models which include digits within their name. Each .* is a seperate column in the layout from the text file, and the second column is the model, which is what I have labeled [10] with.

Hopefully I explained this without much confusion.

For question m, try this:

Code:

#! /bin/sh
while read x
do
    echo $x | cut -d: -f2 | grep -E "[^e]e{2}[^e]" # Assuming 2nd column is car model name
    # The above line will print only those car model names with two e's 
done < carnames.txt
