I put in the wrong code for you sorry
for some reason when I did the grep "Firefox/" it wouldn't work for me.

it came out
86 Firefox/1.5.0.12
570 Firefox/3.0.11
1360 Firefox/3.0.19
84 Firefox/3.5.7
1985 Firefox/3.5.9
17 Firefox/3.6.2
3769 Firefox/3.6.3

Nice one. One small point is that the dot in the square brackets is a special character meaning "any character". You should put a backslash \ before it to indicate that you are looking for an actual dot.

Also, you should place the whole search string in double quotes to be on the safe side.

Before we touch MSIE, any time that you use a grep, you have to think "what data may I have missed out"? You have to check that you are catching everything.

So, I suggest that you run both:

and

to confirm that you have picked up all the Firefox lines.

okay so the numbers in front of the Firefox and version will add up to the total number of Firefox
both codes came up with 7871 that matches.

That was the answer I was hoping for.

Otherwise you would have had to search for the ones you were missing, and then change the grep regular expression to make sure you picked them up.

Right, can you go through the same steps, including that last check, for MSIE?

I am trying right now

There is no hurry. You've been very patient.

If you could also cut and paste an example of one of the logfile entries with MSIE then that would be great, as the original example you gave only had Firefox lines.

See this is different I can get the MSIE alone but do I have to get rid of the () first?

Thanks. You don't need to "get rid of" anything, because all you're doing is searching for text inside a string. You just grab what you want and ignore the rest.

In this case, focus on what you want i.e. "MSIE" and the version number e.g. "MSIE 7.0". But notice that it is different from the Firefox one.

In English, you want to search for MSIE, followed by a space, followed by zero or more digits or dots.

Over to you to write that grep command. It's not much different from the Firefox one.

P.S. When you paste output, it's best to enclose it in <CODE> tags, even though it isn't technically code. It will stop parts of it being interpreted as smiley faces for example.

okay so I got
and the out come was:
175564 MSIE 6.0
125834 MSIE 7.0
15263 MSIE 8.0

Okay so I redid the code so I could get the whole 6.0 instead of just 6

First of all, you really need to enclose the search term in double quotes (I'm not going to tell you a fourth time ).

Secondly, your grep is searching for MSIE followed by a dot followed by zero or more digits - that's not what you should be searching for (see my last post).

Don't worry, try it again.

fixed it

Ok, it's getting late and we've been working on this for a fair while, so this one's mine:

Do you see how that follows the English of "search for MSIE, followed by a space, followed by zero or more digits or dots"?

It's always useful to think of things in your native language before you turn it into computer language.

Right, test it out, and also ensure that you're picking up all the MSIE's, using a modified version of the test I showed you earlier for Firefox.

We're almost there. Thanks for hanging on in there.

oh okay I see that now mine worked too but yours is shorter and yes it worked for me

so I have one more the number of people using any other browser

and before I forget THANK YOU THANK YOU I was ready to give up completely and fail the class.

Great, so the only thing remaining is to determine how many people didn't use either Firefox or MSIE, yes?

yes
