hi,
we all know /proc is about the information of active process,
I have just read an artical which said you can use /proc/cpuinfo,
/proc/net./proc/meminfo etc. to know about some hardware
information .But I want to know how to use with command line? (1 Reply)
I did a search on this, but didn't find exactly the answer I'm looking for. What exactly is the proc directory for? Showing processes spawned by users? I ask because I have some very large files in that directory by multiple users and its affecting my disk usage. Can you limit how many... (2 Replies)

hi all !
Please help me
When I select data from oracle with proc * C prog.
I count the number of rows
For example the total rows is 1000000
but the number of result return is a limit number 5000 for ex
So How can I know this limit (5 Replies)
Perhaps this is a very dummy question but sorry I don't know other place to do it. We just buy a new cluster of Xeon machines but there is something I don't understand and perhaps someone can help me.
The more /proc/cpuinfo produces the following output (just part of it).
processor : 0... (1 Reply)
Hi,
I am trying to calculate the CPU Usage by getting the difference between the idle time reported by /proc/stat at 2 different intervals. Now the 4th entry in the first line of /proc/stat will give me the 'idle time'. But I also came across /proc/uptime that gives me 2 entries : 1st one as the... (0 Replies)
So, I'm looking over /proc/cpuinfo and have a question... I've read that "siblings" refers to hyperthreading, but that seems odd considering the contents of cpuinfo. Here's a part:
model name : Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
physical id : 0
siblings : 4

If you are adding the kernel module without any module parameter passing, it should print out following information to info1 file so that user can make read access to info1 file (via, for example, cat /proc/info1):
• Processor type
• Kernel version
• Total number of the processes currently... (1 Reply)
Hi,
I wanted to understand what exactly /proc/cpuinfo shows?
We have a machine with following specification...
(2x) Intel Xeon 6-core processors
So, ideally it shouls have 12processors, but the output on /proc/cpuinfo shows 24 processors.
Can someone please explain how this is... (3 Replies)

isainfo
isainfo(1) User Commands isainfo(1)NAME
isainfo - describe instruction set architectures
SYNOPSIS
isainfo [ [-v] [-b | -n | -k] | [-x]]
DESCRIPTION
The isainfo utility is used to identify various attributes of the instruction set architectures supported on the currently running system.
Among the questions it can answer are whether 64-bit applications are supported, or whether the running kernel uses 32-bit or 64-bit device
drivers.
When invoked with no options, isainfo prints the name(s) of the native instruction sets for applications supported by the current version
of the operating system. These are a subset of the list returned by isalist(1). The subset corresponds to the basic applications environ-
ments supported by the currently running system.
OPTIONS
The following options are supported:
-b Prints the number of bits in the address space of the native instruction set.
-k Prints the name of the instruction set(s) used by the operating system kernel components such as device drivers and STREAMS mod-
ules.
-n Prints the name of the native instruction set used by portable applications supported by the current version of the operating sys-
tem.
-v When used with the- b, -k or -n options, prints more detailed information.
-x Prints instruction extensions to the native ABI which are supported by the platform.
EXAMPLES
Example 1: Invoking isainfo on a 32-bit x86 Platform
The following example invokes isainfo on a 32-bit x86 platform:
example% isainfo -v
32-bit i386 applications
example% isainfo -k
i386
Example 2: Invoking isainfo on a System Running the 64-bit Operating System on a 64-bit SPARC Processor
The following example invokes isainfo on a system running the 64-bit operating system on a 64-bit SPARC processor:
example% isainfo
sparcv9 sparc
example% isainfo -n
sparcv9
example% isainfo -v
64-bit sparcv9 applications
32-bit sparc applications
example% isainfo -vk
64-bit sparcv9 kernel modules
Example 3: Invoking isainfo -x on an AMD Opteron CPU
The following example invokes isainfo with the -x option on an AMD Opteron CPU:
example% isainfo -x
i386: fpu tsc cx8 sep cmov mmx ammx a3dnow a3dnowx fxsr sse sse2 pause
EXIT STATUS
Non-zero Options are not specified correctly, or the command is unable to recognize attributes of the system on which it is running.
An error message is printed to stderr.
