I feel stupid

[lordtitan]

Okay I want to get a new video card but someone suggested that the video card that I get depends on my CPU. So here is my question how do I check what my CPU is in Kubuntu 8.04, and if possible could someone go step by step for me.


Thanks

'One way' is to use the lshw command, assuming it is installed.

Open a console and type:

sudo apt-get install --simulate lshw

If the program is already installed you will get back the response "lshw is already the newest version." If it isn't installed, you can issue the command:

sudo apt-get install lshw

Once installed, and from the console, type:

sudo lshw | grep CPU

After you provide your password, you'll get a listing similar to this:

description: CPU
product: Genuine Intel(R) CPU T2060 @ 1.60GHz
description: Logical CPU
description: Logical CPU
description: Logical CPU
description: Logical CPU

Your CPU will be identified. Mine is a "Genuine Intel(R) CPU T2060 @ 1.60GHz"

Re: I feel stupid

I'm probably doing something wrong but I have been following your list of commands and nothing shows up, any ideas?

Re: I feel stupid

Do you have the program lshw installed? You can 'copy and paste' the commands I listed. That will ensure you aren't typing something incorrectly.

Re: I feel stupid

Unless I am mistaken the command sudo lshw | grep CPU spurts out one line only. There may be a way of telling bash to spurt out more but I don't know it unfortunately. afaik there is no other way round to simply

lshw

or

sudo lshw

followed by scrolling up the output all the way to CPU.

If you're only interested in the CPU, I believe you can

cat /proc/cpuinfo

and get it that way, too, in detail.

Re: I feel stupid

dibl, the man! Of course - thank you for pointing it out. Would you also per chance know how increase the number of lines of output after a grep command?

BTW, just noticed a news flash from the BBC re some very untoadly behaviour of a certain vice presidential candidate. It's all fun and games across the pond...

Yep, we have a lot of fun with this election stuff -- one would think the President of the USA actually has the authority to do something (other than invade other countries). But we know better ...

OK the famous grep option ... well, it's not my strong suit. "man grep" includes the following:

General Output Control
   -c, --count
       Suppress normal output; instead print a count of matching lines
       for each input file. With the -v, --invert-match option (see
       below), count non-matching lines. (-c is specified by POSIX.)

   .
   .
   .

   -m NUM, --max-count=NUM
       Stop reading a file after NUM matching lines. If the input is
       standard input from a regular file, and NUM matching lines are
       output, grep ensures that the standard input is positioned to
       just after the last matching line before exiting, regardless of
       the presence of trailing context lines. This enables a calling
       process to resume a search. When grep stops after NUM matching
       lines, it outputs any trailing context lines. When the -c or
       --count option is also used, grep does not output a count
       greater than NUM. When the -v or --invert-match option is also
       used, grep stops after outputting NUM non-matching lines.

Is that what you were thinking of?

Re: I feel stupid

Found it:

Context Line Control
-A NUM, --after-context=NUM
Print NUM lines of trailing context after matching lines. Places a line containing
a group separator (--) between contiguous groups of matches. With the -o or
--only-matching option, this has no effect and a warning is given.

Now I can do that

sudo lshw|grep -A 11 CPU

Very nicely done, toad!

Well, your post got me going again after I stupidly and fruitlessly went through the ls man page :-X
