I'm trying to retrieve a single string or value from /proc/cpuinfo, but when I try to extract the model (not the model name) the model name comes with it, also it likes to print it twice...
Code:
model="`cat /proc/cpuinfo | grep model | cut -d: -f2 | cut -c1-3`"
echo $model
All i want this to do is spit out the model number once. (I need to pass it to another script)
Is there a simple way to determine the CPU socket from the output of /proc/cpuinfo. Determining the type of processor is simple enough, but the processor I have (Celeron) has two different possible sockets. The output of /proc/cpuinfo is:
processor : 0
vendor_id : GenuineIntel
cpu family : 15

I've looked on the Intel processor finder web site with appropriate filters, but the stepping values do not appear to match anything.
I have a set of lines as ahown below:
Leon went to school
Leon came back from school..
Leon had dinner...
I have to replace the line containing "dinner" by a single string LUNCH...
I have fedora 14 installed and wish to use/learn kvm. I installed via groupinstall the virtualization group. I see vmx in /proc/cpuinfo. but when I start virt-manager I get a message that kvm is not installed or cannot be leaded into the kernel (to make a long message short). I am at a loss here as to what to do. I run cat /proc/modules and see "kvm 257420 0 - Live 0xffffffffa022a000". also after running modprobe kvm I run [root@fed14 ~]# lsmod | grep -i kvmkvm 257420 0 and see kvm there.

I have just bought new PC (Intel mother board "Intel DP43TF ATX" and Processor "Intel Core 2 Quad Q9550"). and I have installed centos 5.3 32 bit.
NOTE: All cores are enabled in BIOS.
When I issue below command, it shows only one core (not 4 cores): what could be reason!
# cat /proc/cpuinfo

There is a computer with two "Xeon(R) CPU X5550 @ 2.67GHz" CPU. The Hyper-threading is enabled, so it looks like 16-core system, but really there is only 8 physical cores.
I know that when hyperthreading is enabled, each physical core is splitted into two virtual cores. I want to know, which pair of virtual cores shares a physical core and which are not. Or, how (in what order) will Linux enumerate HT-cores comparing to real cores. (enumerating is done for sched_setaffinity and taskset masks).
I have a dump of /proc/cpuinfo file from the system.
I think there are possible:
CPU0-CPU7 are not sharing phys. core. CPU8-CPU15 too. But sharing is in pairs CPU0+CPU8, CPU(i)+CPU(i+8) and so on. or CPU0+CPU1 are from single physical, CPU2+CPU3, CPU(2*i)+CPU(2*i+1). or exotic CPU0+CPU15 sharing, CPU1+CPU14 ... or random?
The hard moment in this case is that there are 2 physical dies of CPU (two sockets), and usual recommendation of using "physical id:" field can't help
The cpuinfo:
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 26
model name : Intel(R) Xeon(R) CPU X5550 @ 2.67GHz

After I assign a string to a variable, I know that the print function will remove the single quotes around the value, but is there a way to assign a variable without the quotes around the value? for example:
a = open('/usr/lib', 'r+')
b = f.read()
c = x.replace('.xx','yy')
d = ?
c returns the value with quotes around it print c returns the value without the quotes Is there a way to assign a new variable (d) which will equal c without the quotes? I need a new variable which has the quotes omitted because from there the script will take the value of the last variable (which is a path to a file), and tar up that file. It won't recognize the path to the file if the value has quotes around it.

View 1 Replies View RelatedI've been trying to understand pthread in C a little better. So I made a simple program that takes in a string from the command line and creates a thread to print the string. I've looked online and copied the basic concepts but there are something things I'm confused about. The programs works just fine, but I have questions. Here's what I have so far.
[Code]....
One thing I'd like to know is why the 3rd argument in the pthread_create function which is my SendMessage function needs to be typecasted to a void pointer and then send the address of the function. Also as for the 4th argument, I would see typecasting to void pointer in some of the pthread examples I saw online, but in my case I'm passing a char pointer, would this be correct? In which case would I ever want to pass a void pointer?
Do I need a pthread_exit(NULL) in my main and in the SendMessage function? If so, why? I added the sleep() function so that I could let the pthread_exit function in my SendMessage function execute first. I simply saw that the online examples on pthread had pthread_exit() in both locations.
I need to creates string suffixes out of a Reference string. for eg. suffixes of abcdefg will be
1)bcdefg
2)cdefg
3)defg
and so on...
create an array of pointers to point to the first few characters and then use that pointer to print the rest of the string.But when i print using the pointer i get GARBAGE values! shudn't std::cout<<ptr[w] print the string following the char it is pointing to? why do i get garbage values?
So if I'm given a location of a file like:
How can I just take the type of the file at the end? I know I can use strrchr() for a period to get the pointer to the period just before file type. Is there a build in string function that will just take the rest of the string from a certain point on forward in the string? I know it wouldn't be much work to make it myself, but I figured I would find out if it already existed before doing it.

is there a way to make the /proc filesystem writeable? With aufs or unionfs i can't join the /proc filesystem with a writable directory directly. But i think it should work by using one of this file systems.If i try to join two dirs write-proc and virtual-proc Code: mount -v -t aufs -o dirs=/tmp/write-proc/:/tmp/virtual-proc/ none /tmp/joined-proc/ and afterwards make a bind mount /proc to virtual-proc Code: mount --bind /proc /tmp/virtual-proc/ i can't see any change in /tmp/joined-proc.

I want to check whether a USB is plugged in its slot from a C program. I want to make use of /proc interface for the same. During my reading i found that /proc/bus/usb/devices will tell how many USB devices are currently present.
So whether i can open this file and use stat call to identify whether the size is 0. If size is 0, i can assume no USB present. Else i can assume USB is present.
Whether my understanding correct. If USB inserted, how can i check the folders present in the USB stick.
