When you do:
head -3 statistics.dat | grep '0890'
this selects the first 3 lines and does not display them, but instead forwards them (pipes) into the next command for processing, and of course the grep will not find that string in that set of lines.
If those header lines were very easy to identify, a single grep command with two search arguments could do it, such as:
grep -e Header -e "^0890" statistics.dat
If not, do two separate commands:
head -3 statistics.dat
grep "^0890" statistics.dat
The carat is anchoring its search to the very beginning of each line (which I think is correct for your data) so that it will not accidentally find the search string somewhere else in the line. Here is a script that you can execute with a parameter:
hi all. thanks for looking
i am doing some homework.
one question is that when type
wc
and then how to tell the program that we have finished entering data?
also
why do some operating systems report 22 as the number of bytes in the file above, while others only 20?
thanks so much,... (1 Reply)

Hi,
Well my title isn't very clear I think. So to understand my goal:
I have a script "test1"

xvkbd -text blabla
with xbindkeys, I bind F5 key in order it runs my test1 script
So when I press F5, test1 runs.
I'm under Emacs/Vi and I press F5 in order to have "blabla" be... (0 Replies)
I am going through the Unix Made Easy second edition book by John Muster. So far it's been very informative and I can tell it may be a bit out of date.
In one of the exercises it talks about the "sort" command and using it to sort column's of data etc. The "sort" command has changed a bit and... (1 Reply)
Hi all,
I wish to know whether Unix can access window's file in Unix's terminal?
Apart from that, how to copy files or share files between Window and Unix? I get to know of secure copy, however, my company's Unix does not support the feature of secure copy? Any other method for me to share/... (5 Replies)

acpidump
ACPIDUMP(1) General Commands Manual ACPIDUMP(1)NAME
acpidump - dump a system's ACPI tables to an ASCII file
acpixtract - convert ASCII acpidump output to raw binary table
turbostat - gather performance statistics
SYNOPSIS
acpidump [options]
acpixtract [options] [filename]
turbostat [options] [command [arg]...]
DESCRIPTION
This manual page documents briefly the acpidump , acpixtract and turbostat commands.
turbostat reads hardware registers and gather statistics on the processor clock frequency and C-state usage. Works properly on Nehalem and
newer processors and on Linux kernel 2.6.30 and later versions.
OPTIONS
acpidump options are as follow:
-a, --addr 0x1234
look for tables at this phisical address
-t, --table DSDT
only dump table with DSDT signature
-o, --output filename
redirect output from stdout to filename
-b, --binary
dump data in binary form rather than in hex-dump format
-l, --lenght 0x456
works only with --addr, dump phisical memory region without trying to understand it's contents
-s, --skip 2
skip 2 tables of the given name and output only 3rd one
-h, --help
outputs an help message
OPTIONS
acpixtract options are as follow:
-a extract all tables, not just DSDT/SSDT
-l list table summaries, do not extract
-s<Signature>
Extract all tables named <Signature>
OPTIONS
turbostat options are as follow:
-v makes turbostat more verbose
-i <sec>
polling interval, default is 5
When given a command turbostat runs it and outputs statistics gathered while the program was running.
EXAMPLES
Dump the DSDT table to the file DSDT.aml in binary format (this can be disassembled later with iasl(1)):
acpidump -b -t DSDT -o DSDT.aml
Show the FACP table:
acpidump -t FACP > FACP.dat
acpixtract -a FACP.dat
iasl -d FACP.dat
Dump and extract all ACPI tables:
acpidump -o DSDT.dat
acpixtract -a
Parse APIC tables:
acpidump -o DSDT.dat
acpixtract -sAPIC DSDT.dat
